Hi I bin asked to explain my project a little more, BEAR with me iam pretty slow on the computer.
First I took 3 ford 9 " diffs and used 10 " of the ends I turned the sawed off end out to fit a 6207 bearing. I coped them through a 4x4x.375 square tubing.I then turned the axeles down to fit the 6207 and put a keyway out the end.
the axels are 36" apart. for a 72" outside c/c. I got the bottem formed out of 10 guage with a tunnel for out board use. I have double roller 60 HD in a sepentine fashion covering all sprockets per side with a super strong slack adjuster.
Outside to outside with tires it is 74"
The dana 44 open diff does the steering with the nissan vented disk brakes. If this thing works out good I was thinking of putting a ARB LOCKER in it for those nasty situations where no steering is requred ! The diff is out of a 1995 1/2 ton ford front high pinion. I had to make bushings to mount the seals for the extended axels whitch have 1 1/4 pillow block bearings on the outside.
The jetta diesel still needs the spider gears reworked (next on the list) It was a transaxel and is now mounted inline, so it drives of one side now needing a spool.
The main frame is out of steel but the body is going to be aluminium.
the tires are goodyear super teera grip 31x15.50
I have a few small things yet to figure out. Like the size of master cyls for the calipers and fuel tank shape, Final tub shape, Cv joint to ujoint adapter
Overall its going pretty good. I will try to do some pics over the holidays.
Its bin a couple of year project so far , Not to ambitious sometimes.

Enough for now
Curtis.
