Wheels from the semi boneyard, 6 22's.
Single wheel 1 ton rotors. These are about 3.5 inches shorter and use all the same bearings and brakes.
Control arms lengthened 1.5 inches with cups sunk in about 2 inches.
Cab and chassis rear end I found on craigslist, I don't remember exactly how much shorter it is than the Dana 70HD I had. I want to say it was about 6 inches narrower on each side.
Also, I did a rear disk conversion. Got the caliper brackets from 4wdFactory and the rotors and calipers are from the front of a 80's Chevy 3/4 ton 4wd.
Old frame.
Start of the new back half.
Watts link and 4 link installed. I jogged the frame in to keep the bags as far apart as possible.
First time on the ground with the front put back together.
Bed on and trimmed for the wheels. I already had tubs in the bed so those had to be cut out also.
