Stretched Flatty Specs

[CAVE]

There are quite a few stretched willys on this board, but I haven't been able to find a picture thread comparing them. It would be cool if we could start a bit of a spec sheet with pictures. There are a few threads scattered here and there discussing body mods (stretch behind the door or in the door), wheelbase (longer wider), belly height (flat skid with or without a hole in the hood?), suspension setup (soa vs sua vs links), frame mods (custom vs modified stock vs non jeep frame), and trail weight. The hard part is searching it all out when trying to plan a body stretch and some of the same topics seem to come up a lot. This could be a great tool for everyone wanting more... or less. Unless someone already has this all lined out please post your...

Wheelbase
Tire Size
Belly Height
Measurement to the Top of Your Hood/Grill
Suspension
Stretch Mods
Frame Origin
Drivetrain (include axle wms)
Vehicle Trail Ready Weight

Please include a picture on level ground from the side and front if possible. Also a link to your build if you have one. A note on performance and things you would change might help too. Thanks for participating.



An example from Silent Hunter's Willys Build (feel free to post and fill in the gaps/mistakes and I'll delete this example, hope you don't mind me using your jeep)

Wheelbase 101"
Tire Size 35s "for now"
Belly Height
Measurement to the Top of Your Hood/Grill
Suspension SOA BDS 2.5"
Stretch Mods 9" in door 7" behind door
Frame Origin Custom 2x4x.188
Drivetrain 4.3tbi, sm420, d300, dana 44s with wms?
Vehicle Trail Ready Weight




Here are some others awaiting specs. It doesn't have to be stretched or heavily modified to contribute useful information

[csutton7]

Wheelbase---109''
Tire Size--39.5''
Belly Height---23''-25" need to get front end together for final measurement

Drivetrain (include axle wms)--built 5.0, zf5-42,atlas 4spd,front dana 60/rear 9", wms69"
Vehicle Trail Ready Weight--???

[2a_toys]

Here's mine. Didn't stretch the tub any, only the wheel openings because I want to put a soft top on it. Hind sight I would have moved the motor back about 2 inches and stretched the hood a couple more inches to fit a Taurus fan. With the mechanical fan and shroud it runs hotter than I like on a hot day because I can't get the RPM's up enough for the fan to be effective.

Wheelbase---89
Tire Size--35
Belly Height---can't remember
Measurement to the Top of Your Hood/Grill-- haven't ever measured
Suspension--4.5" lift Rubicon Express YJ spring under axle
Stretch Mods --- 3.5" at hood and fenders
Frame Origin--51 M38a1 (same as early CJ5). stretch 2" front, 4" back
Drivetrain (include axle wms)--TBI 305 SBC, TH350, D300, Waggy axles 61.5 wide wms-wms for front and 58 rear.
Vehicle Trail Ready Weight--3500ish

I didnt stretch the body on mine any either. (for a soft top) My wb is 90", stretched about 4" in the back, and pushed out 6" in the front. Build thread in my sig.

[APU]

this would be mine.
started out as a 46 cj2a. boxed the frame and added 2" up front and 2" out back. the body is not stretched, but the rear wheel wells are recut. the wheel base is 88 inches. i used stock yj springs in a soa setup.

#1 on the left is a 1951 M38 known as the mojave limo. built in 1995 it was streched 24" between the door well and the rear tire. the frame is a 72 cj-6 with a 3/16" strap front to back on the bottom frame rail. rear cross member is 3" channel and 3" angle with a reciever hitch, front is 3/8" plate cross member/winch mount. all new spring and shackle mounts of 3/16" or 1/4" stock. ron davis rad. 400+hp 350/700r4 dana300 dana 44s with 5.38 gears an detriots. YJ 2 1/2"lift springs SOA, scout power steering box. normally when i do a repower i carve out the firewall set the biggest rad i can squeeze in,mount the engine then replace the firewall. this one has a 3" setback with lots of room for air flow and work space. at least as much as you can expect when cramming 9lbs of crap in a 3lb sock. the key to building flatties is space managment and compromise.

i didn't strech the bodies in the door wells because i think it ruins the look of the flat fender and i belive it doesn't give you any extra room to get in and out with the seat most of us use now.

btt

Hoping to see more examples.

Great thread idea.

[CAVE]

The reason for starting this thread was to help me make some decisions on my build. I guess I'm far enough to put up a picture and some specs. Still have a bit to go though.

Wheelbase- 100.5"
Tire Size- 35/12.50/15
Belly Height- 17.75" currently (but shooting for 18-19), everything tucked above the frame
Measurement to the Top of Your Hood/Grill- 46.5" (again, planning on a bit taller)
Suspension- OME 2.5" yj springs SUA
Stretch Mods- I didn't have a stock tub to compare to, but a few inches in the door and and few behind the door. Basically did body "skins" to look what I perceived as "right" for the wheelbase I wanted. (I like the goofy cj6 look)
Frame Origin- 2x4x.120, I didn't do the 4" stack frame, I added 2" for a total 10" instead of the 8" of a stacked frame to get the drivetrain under the hood and above the frame
Drivetrain (include axle wms) 4.3L, 700r, np231c, waggy axles (58-62")
Vehicle Trail Ready Weight- Not done yet, but I'll get there eventually



A little more done now and driving...

Looks like you sent the upper front shackle bolt through the frame which appears to enable the movement of an extended shackle without suffering an all-under-frame mounted, long, low-hanging shackle catching everything in its path.
Great idea. Seems a nice shackle angle, too.

I'd guess that the thru-frame shackle mount also solves some caster angle issues with ext shackles and 2.5" lift springs. SOA, right?

Do you have a saginaw steering box mounted inside the front frame horn?
If so, does the mount or gear box interfere with the upper frt shackle bolt?
Maybe the gear is mounted at an angle?

Or does the rig have another steering setup?

Is the rear upper shackle mount also sent thru the frame?


At some point as you're workin' on the rig and if it's not too much trouble, I'd like to know the following:

WMS inches (save me a search on waggys):
Rim offset:
Track width:
How close the tires come to the frame/spring, fore and aft, at full lock.
With regard to only frame/spring contact, what would you say is the tallest tire you can run with what knuckle angle?


I think I agree with most everything I see except for the door stretch that I'd keep stock for off-the-shelf soft top doors.


Very interesting take on stretching a FF. Looks like you do good work.

[CAVE]

Do you have a saginaw steering box mounted inside the front frame horn?
If so, does the mount or gear box interfere with the upper frt shackle bolt?
Maybe the gear is mounted at an angle? Yes, No, No. I spaced the steering box out from the frame enough to clear the shackle.

Is the rear upper shackle mount also sent thru the frame? Not yet, but it will be.

WMS inches (save me a search on waggys): I believe stock front is 62" and rear at 59" (from memory which isn't that great)
Rim offset: 15x9s with 3.75 backspacing
Track width: approx. 76"
How close the tires come to the frame/spring, fore and aft, at full lock.
With regard to only frame/spring contact, what would you say is the tallest tire you can run with what knuckle angle? I'm not in a spot at the moment to full lock the steering, but I did run 36s with a very similar setup on a previous jeep. Frame width is waggy perch width at 30" inside.

I think I agree with most everything I see except for the door stretch that I'd keep stock for off-the-shelf soft top doors. I will probably be building a custom top and doors at some point, but that is a long way down the road.

I hope that answers your questions. I'm considering a build thread, but not sure yet.

*Edit* it is SUA

[1946CJ2]

Cave, is it soa or sua?

[4x4Poet]

SUA!

That makes the rig even better.

Thanks for the info.

Nice Jeep...
If I could do it all over again, I would stretch those 6” at the doors.

Yeah, I'm 6'4" and I wheeled my stock flatty for 10 years. I wanted it to look as close to stock but i need the leg room!

[lebowski]

Some nice photos and diagrams of factory 6x6 WW2 Willys. Notice the widened front fenders, widened body tub, but hood remains original width. Might give some additional ideas for this thread.
