Willy Nilly - My CJ3a Build

As a long time Pirate surfer, I figured it was about time I posted up some of my project progress...

After graduating school in Nashville, TN where I grew up, I got a job and moved up north to Saginaw, MI. The new-found money, time, and urge to build something led me to drive from Saginaw to Charleston, WV to pick up what turned out to be a much rougher than I expected pile of flatty parts. I started with a frame, about 1.75 tubs, and a whole lot of ambition.

When I was in school, I participated in Baja SAE... designing, building, and racing small buggies, but I have never done anything on this scale. The name Willy Nilly comes from the manner in which I started gathering parts... from just about everywhere and everything, with little regard to how it would all end up going together. That said, it's been a long road so far, and will continue to be that way, since I like to eat instead of spending all my money on parts. I started the gathering and building in the Fall of 2010. Since Iím a big sissy when it comes to cold, I donít work through the winters much, so progress is slow.

I picked up a pair of Scout Dana 44ís that need a ton of work, but they were the right price. I decided to try some 4.5Ē lift YJ springs that I plan to run SUA. I have a modest stretch (6ish inches) by relocating the spring hangers. I plated the stock frame (yeah yeah yeahÖ) The power will come from a TBI Chebby 4.3L backed up by a SM465 and twin sticked NP205. Intercoís blem website hooked me up with a set of 36x12.5 TSL SXís that I mounted on black steel wheels. The cage is my own design and build at the same time special, which will contain a pair of Corbeau SS seats, 4 or 5 point harnesses, and a 15 gallon fuel cell.

But enough jibber jabber... on with the pics!


This is what I showed up at home with.


Some more of my pile of parts. I ended up with a frame, a windshield, two grilles, two sets of fenders, two hoods, one in tact body, one body cut into three pieces, a seat frame, and various other little pieces thrown in too.


Something seemed a little fishy when I was unloading, but I wasnít quite sure since Iím a Ford guy and not a Jeep guy.


A little work with the olí grinder revealed some yahoo had covered the entire tub with an extra layer of sheet metalÖ


I never figured out why, since the stock steel isnít terribly rough or rustyÖ there are 6ish layers of brushed on paint though.


Then I found this. So much for just having an extra layer. I didnít want the comp cut look, so out came the trusty plasma cutter to do some surgery.


I cut off the rear fenders and replaced them with sections from the aforementioned other tub.

The framework started by cutting off some geniusís attempt at a stretch. Not exactly what I had in mind.


I capped the front and rear of the frame with 2x4 crossmember/bumpers. Hereís the obligatory welding picÖ nothing fancy.


I boxed the frame with 1/8Ē steel. Looking back, I probably should have just done the rectangular tube frame, but Iím stubborn, and like punishing myself.


Thatís my take on bumpers. Nice and simple, but I think it will prove too wide for the tires to be able to turn.


Hereís the mock up of my drivetrain. The red paint was done by the guy I picked the motor up from, and the intake was a $30 chinabay special.


I donít want to cut the hood, so Iím stuck hanging the goods below the frame. Iíll have to skid plate it for sure.


And itís gonna be a tight fit width ways too.


With the bellhousing about a half inch from the firewall, the transmission pokes through in just the right place. I cut the hole in the floor larger for ease of install, but I donít think it needed to happen for clearance.

I borrowed a bender from a coworker, and started up on the cage. (I moved to a house with a biggerÖ still smallÖ garage about this time)




I prefer this style of cage to the ones with discrete A, B, and C pillars. I chose to slope the ďroofĒ up to accommodate a little more head room. Iím only 5í8Ē, so I donít think Iíll have much trouble, but I have tall friends. Weíll see how that goes.


Itís gonna be snug for sure.


I notched the wheel wells to scoot the seats back a bit, and bent the B pillar bars to follow the lines.


Iím a bit of a node nazi at times, so my B and C pillars are connected at the bends, and the hip bars continue that line.


The roof is bent up to give yet a little more head room. I donít really have a good way to add diagonals in the B pillar, so the rear triangulation will have to do. When I throw the harness bar behind my shoulders, I plan to try something to give it more lateral strength.


My head room should be okÖ itís closer than Iíd like, but if I sit any lower, I wonít be able to see the front of the hood through the windshield. Rollcage padding is on the list.

I have the front standing on its own. Iím 6 inches from tire to fender. To clear the springs, and due to other reasons, I ended up with 17x9 wheels with only 2.5 inches of back spacing. It pokes a little more than I would like, but I donít think itís too bad. I should be around 77 inches wide overall. You can see how I mounted the springs to stretch the wheelbase. The rear will be the same.

Thatís all I have for now. I ended up grabbing a different and more complete engine a couple weeks ago. I have to switch them, figure out what wiring I want to keep, and tidy up the engine bay. I need to mount the fuel cell and start gathering lines, pump, etc. The steering is nonexistent, as are the brakes, driveshafts, and other little stuff.

I know Iíll have questions, as Iíve been watching other builds in here, but I hope you enjoy for now.

Are you still in Saginaw? I'm just over in Hemlock. If you are still around I'll have to come check this out sometime. I'm building my own flatty but I'm not nearly as far along as you are.

I might have missed it but what are you running for axles?

Looking good. I'm liking all these new builds popping up in here. Keep at it. I'm the opposite and hate working on stuff when the weather is nice. I'd rather be out enjoying it then, so I'm stuck working in the cold.

Yeah, I'm still in Saginaw. And to your comment about not being as far along as me... the 80/20 rule is owning me. I really don't have that much done. It just looks that way, since they're all big things. Getting it running and moving under it's own power is a bunch of little things that will take a lot of time.


I got a little more done today. My seats are mounted. It's cozy for sure. As far as seating position, I hope I got it right, since the seats are hard mounted and not on sliders at all. Of course everything is just tacked for now, so I could change it later if need be. It's hard to tell if it's good without a steering column or pedals, but I hope to be able to locate those based on where I'll be sitting.







I rolled the rear axle into place too. I need to place an order with Ruff Stuff for some u bolts and plates before I can mount it, but it looks like I'm going to have to do some cutting.



I really don't like the comp cut look, so I'll probably be doing something like the sharpie line. SVARAS's rear wheel well lines are pretty similar, and I like the way they look. I just hope that my tires don't travel rearward too much since I have my shackles mounted in the rear.

The jury is still out on the details, but the plan is to be tucked up as high as possible, flat as possible, and light as possible. It'll be the same tube as the cage (1.75" OD x .120" wall DOM) and I plan to skin it in plastic or aluminum rather than steel to keep it light.



All I have so far is enough to hold the transmission and transfer case up. I'll probably throw another member in the vicinity of the bell housing, and something behind the transfer case too.

I'm trying to decide what to do inside my axles.

I plan to use the Jeep for general trail riding, occasional trips to the dunes, but would like to be able to put it on the road once or twice a month when it's nice out.

Keeping in mind my SM465/NP205 combination, I was thinking a 4.88 axle gear would be in the right range. That would give me a 63:1 crawl ratio but be able to run 65 mph at 3k rpm. Does this sound reasonable? Too much gear? Not enough?

As far as lockers go, I'm thinking spool in the rear and automatic up front. Probably a Detroit, maybe a Grizzly. Since I'll need a new carrier anyways, I have pretty much ruled out lunch box lockers. I'm afraid to run a spool up front due to breakage and trail manners. Any thoughts about that?

I run a welded diff up front on my trail rig (dana 60). I also have full hydro though. If you were running hydro assist and lockouts I wouldn't worry about a spool up front, but if you plan on regular power steering and drive slugs I would say no to the spool.

As far as the gearing, that sounds about right. I'll be at 83:1 crawl ratio with 4.88's on 37's or 4.56's on 35's (I haven't decided for sure on tire size). Cruising rpm will be about 2850 either way. The 205 seems a bit overkill for your application. Any reason not to run a Dana 300? You'd get a little better crawl ratio and the case and adapter is more compact for rear driveshaft length.

So yeah, the NP205 is probably overkill, too big, and is heavier than I would like, but I got it on the cheap with the transmission. Also, I shouldn't run into any problems with breaking it.

Last night I priced out gears, install kits, spools front and rear, and chromoly shafts. Holy crap! Over 1500 bones! I probably don't need the upgraded shafts, but I'd hate to find out the hard way, especially after having everything apart anyways.

wow man, very nice build! and nice to see a tri-cities rig here. I grew up in Midland and most of my family is still back there. my sister and her guy are jeepers as well, so when we can come up with a tow rig we plan to bring our willys back home to visit.

I'm tri-cities too. I know of at least two other flatties in the areaish. We could have a flattie convoy! Well if all our projects are done.

Ruff Stuff rocks!

So a year ago (april 16, 2011 to be exact) I ordered some shackles and a Ford 8.8 simple swap kit from Ruff Stuff. The parts came in very fast and super high quality (as usual) but I ended up not using an 8.8 and called to see if I could return them. Expecting to have to eat the cost, I was shocked when they told me to throw them in a box and ship them back for a full refund! No restocking fee, no questions asked! I sent them back and ordered some different parts from them, so when they get here, I'll be able to take the jack stands out from it.

Cliffs: Dan at Ruff Stuff (aka Gravelmaker) is the freaking man!

Look Ma, no hands!

So as of this evening, there are no jackstands holding it up. Ruff Stuff sent out the parts I ordered from them very fast, and I got the rear axle mocked into place in short order.









Don't mind the rough cut on the rear fenders, I'll make it "pretty" later. I'm having to take more off than I want, but there's not much I can do.

Now that I have things generally where they're going to go with most of the weight on the springs (minus the fuel cell, me, some parts, etc.) I can get some correct-ish measurements.

Wheelbase - 93"
Pumpkin Ground Clearance - 11.5" (15 psi)
Belly - 16"
Rear Driveshaft Length - 16"

I ordered axle goodies today, so in a week or so I should be able to tackle the spools and gears. I'm holding off on chromoly shafts for now.

awsome build, I will be watching... I am also in saginaw ... you and beavertown got me itchin to start working on my flattie.
if your interested my brother and I figured out how to shorten and clock that factory adapter between the sm465 and 205. I can't remember exactly how much we gained but I think it was 1 3/4 inches and clocked the 205 up 30 degrees. He is running that setup in his '79 CJ5.

i love the stance, and have to say that is probably one of the nicest looking cages i've seen in a flatty!

Thanks for the kind words! I've been slacking lately and haven't made much progress.

As far as clocking the 205 goes, I would love to do that, and have no problem fabbing up a new figure 8 adaptor to do so, but I'm pretty sure it wouldn't fit between the frame rails after that.

I did switch out motors, and have started to do a little wiring. I also mounted the fuel cell, and have been making decisions on how I'm going to plumb the system.


I've been convinced to form a 24 hours of lemons team with some guys at work, so fundage will be stolen from the jeep for that... but I still have plenty of stuff to do that's free or already paid for, so progress shouldn't completely halt.

Man, I haven't touched the thing in months... I'm building a 24 hours of lemons car right now for a race in October, so my time and funds are shuffled towards that for the time being. I still have plenty of "free" work to do on the jeep, but haven't been doing it...
