I also remember I had really bad Death Wobble now after I swapped on the 44's. I under went alot of changes to figure out my problem.
With my shackle flip I replaced all the rubber bushings in the leaf springs and also braced the back if the front chevy hanger.
The original hanger has a piece of angle iron that bolts to backside of hanger below frame and underside of frame itself. In order to mount it I had to grind the heads of the factory rivets holding the rear crossmember on and run through bolts to matching holes on angle plate.....meh too much work
I made up some gussets out if some 3/16 plate and stick welded them on.



It's not exactly easily removeable now but its seems to be a permanent solution I'm happy with so it's ok..

So back to the driveshafts. I started with a driveshaft I found at a wreck that was too long but had a 1350 slip yoke. Took the shaft to my local driveshaft shop and we ordered a 1350 cv. I wanted all sealed spicer joints installed so in order to do that we ordered all the cv parts seperarely and built it when they arrived. He put it all together with a balance and I slapped it in for mock up.



I left the ubolts loose and new spring perches un welded with the driveshaft bolted up. With the weight of truck now on the ground I rotated the diff yoke down 1.5 degrees from being inline from driveshaft to allow the normal torque load twisting up under acceleration to keep the joint parallel. This is where simple researching and educating yourself paid off big time.
With the cv joint my angle on shaft was a total of 21 degrees alot and too much for a single ujoint to handle. With the now cv the ujoints shared the angle at 10.5 degrees each which is now acceptable.

With that done I moved onto the front suspension. The old leafs were something like a re arced 4" stocker or something and they had bad bushings! Was this my death wobble?? Never really did pinpoint it to one thing as I was doing a big overhaul on all this suspension/ driveline. I replaced the front springs with pro comp 6.5" newer style super duty leaf springs. The price was right at 300$(CND) for the pair with new bushings already installed. The only mod I had to make was take a die grinder and open the front spring hanger up just a little as the new springs had a bigger bolt to slide through. Other than that I made a rear set of little bit longer swing shackles out of some 1/2" flat bar and bolted the up. At this point I ditched the stock ubolt holders and flipped them the other way for better clearance. Used a piece of heavy overkill 5/8 plate that I punched the holes in at work and got some new 9/16 ubolts made for it. Easy fix and worth the effort

With the suspension work now complete I now wanted a brace from the divorce tcase to the upper crossmember like some 4x4's came with but were limited and hard to find. I built one myself out of some 1" round bar with the last 6"s threaded with a custom plate that bolted to t case . The upper end bolted to the top crossmember through an angle tab with a hole in it. The top nuts were sandwiched with a rubber bushing to take the vibration.
My next step was I put on a new set of aluminum wheels.




I loved the look of these and i had to have them. No more white spokes!
While I had the wheels off I put a good handful of copperhead bb's in each tire to help solve this death wobble...my last step was I put 2 , 1/8 thick washers under the caps and steering arm for front kingpins to put some more preload on the spring. After all these upgrades the truck went back on the road and the death wobble went away!!

Truck was running great and I just for fun I put my bros 49's on for a bit just to see how they ride.



They were surprisingly very smooth I couldn't believe it.

Before this point I made a set of tube doors for the summer or just for better visibility out wheeling here's how I started



I made the mounting bracket out of 3/8 plate with some bent 90 square bar to hang doors on square tube recover on tube doors them selves. I want it to open and close but also i could slide them straight up off the hinge and run no doors at any time


The locking pin was a little box I made with it spring loaded to lock into a tab which could bolt to original striker bolt location so it could be removed. I ended up modifying the locking tab so it had a ramp about and inch long so you could slam door and the pin would ride up ramp then spring load drop into hole to engage it locked it. I hate finicky tidly work like this but it worked out pretty dam well.

This pic was how originally had it but it rattled like crazy until I made the tab with ramp and hole to replace this... No pics of that right now.

Sweet ass truck! I look at your pics and look out my window at my primered 74 thinking I need to start getting busy on mine. Have to wait till summer-work is seasonal.You've given me some good ideas though. Nice job!!

Thanks man! I got a collection of soo many pics of building, wheeling, tech and some vids I'm just trying to piece this all together in the right order.. I think I'll basically cover all the necessities on everything you need to do ,fix or modify on one of these old trucks. Believe me it wasn't a one time build I changed lots of things along the way this is just the first chapter. I'll have another section where I redo some big changes aging after beating the snot out of it offroad... Lots of good pics to come.

Now I still havnt really 4 wheeled my truck too much yet but that is soon to change!! My body panels only stayed straight for so long.
First off though I needed a good rear axle. My 60 front was Detroit locked and I found a rear SRW d70 that got a rear disc conversion right off the bat..


Basically I couldnt bring myself to buy caliper brackets when I could make my own!
I basically took a piece of construction paper and a measuring tape and starting tracing. I came up with this.

Looks pretty good and you're making a lot of progress. How do your homemade rear spring packs ride and how thick are they? Looks like it could rival a dually.

Only critical part was the center to center if the threaded holes.


Well it fit perfect!
I cut the original diff mounting flange right off. That is where the bracket had to be welded and this way there was no spacers.

I used my angle finder on my diff that was already installed then tilted this diff to the same so I could clock the bracket to have caliper bleeder to screw as vertical as possible to allow it to be properly bled of fluid. That is the best thing about this setup especially with a big truck like this with the diff having to be rotated up alot for a cv driveshaft.



While I was at it I cut off the stock shock tabs and made some new ones for better clearance

Yeah theres some added leafs in there from another spring pack, mainly just the short ones. After the shackle flip it flexed good in the back.
This is fast forwarded a little bit but here it is on the ramp.

My next big purchase was a Detroit for the D70. Not cheap at all but it had to be done.

A 14 bolt axle would of been much cheaper to build but I'm pretty picky on some stuff and I like some of the advantages of the d70 over the 14 bolt like 35 spline "slightly" bigger axles , better ground clearance and the fact they came in a ford...
Pattern checked out good with like .010 backlash and it held up with no issues. Replaced all the bearings as well with new oil slinger seals and so on..

Sweet. I'll be keeping up on this one. It will really help me with what I'm gonna do. I guess I,ll have to come out of pocket so I can start posting pics when I get started. Keep it coming!

My next weak links on the driveline was the front shaft and the short divorce one. The front was a breeze with a new 1350 weld yoke on one end and a 1350 slip yoke. The divorce not so much!

Heres the deal with the divorce and it's a good tech fix for anybody rockin a 4 speed np435 tranny with a divorce. My short divorce was made at the driveshaft shop with a 1350 weld yoke and 1350 skip yoke. I purchased all new t case side 32 spline fixed yokes from NWF but the output yoke fir the back of the tranny I couldn't find one! I called everywhere even high angle drivelines in Cali. They said " no one makes one". So I dud what any backyard mechanic does and gets creative.
The spline count is 28 on the tranny. I worked with my driveshaft shop checked the catalogue and found a ford 1350 9" yoke is 28 spline. Ordered the yoke slid it on and it went on but it was uber sloppy! Well next plan..
I worked with my machinist and basically I got him to take the original np435 yoke and machine it ALL down so it was just basically a tube with the splines . Next we took the 9" yoke and machined out the splines until it was a "C" hair smaller then np435 tube. 9" yoke needed bevel cut in it on the tranny seal side so weld wouldn't cut seat and would be flush. We heated the 9" pressed in the splined tube and I welded with a high nickel rod. I used a standard flux core wire to tack it at first and they cracked telling me I needed a special rod. I dug out the cracked welds pre heated and welded with ni rod then allowed to cool slow over the next few hours in a bucket of dry sand to hold in heat.
It has held up to this day and I've flogged on her good!

I recently discovered on here that there is another option in a tranny solution if you must have all 1 ton ujoints like me!

Here's the thread link

Ok so at this point my truck is pretty built up and it has some good parts. This is the part where I start to finally have fun with it and do some wheeling..

My first real 4x4 event was in East Sooke in a private competing called the frogstomper poker run. I showed up a little later than everyone else and I didn't know the trails all that well as I've only been a spectator before. Truck started off good



Wow those body panels are straight..



Everybody kept asking me why I had a liscence plate on my truck as most were trailered there. I told them I drove it there (about a 45 minute drive 1/2 highway) and I plan to drive it home

I wheeled some good hard trails with mud, rocks, tight trees, side hill ditches man this course is like the tank trap. So much fun.

I did end up snapping all 3 grade 8 steering box bolts right off the frame early in the day. We walked down to the bottom and found 3 grade 5 bolts that were way too long and we used sockets under the head as spacers. It worked all day surprisingly! EDIT: I forgot to mention later I drilled all three holes on box open to run 1/2" coarse grade 8 bolts for a proper fix!!
We wheeled all over the mountainside and then went to the bottom to the beers gardens that was set up. One last obstacle was a dried out " mud drag" as a timed event. I gave it a look over and said what the hell. Dropped it in second gave her shit hit a hard rut and...

This happened right in front of the beer gardens and I got a good cheer.

No one was hurt and there was 3 of us in there.. Lol
Luckily for the roll cage we all had something to grab onto as I had the half doors on!
