Re: subframe question

I have a 57 one ton and I installed 73 3/4 ton frame on my truck and it could'nt have worked out better, I cut a c shape right behind where shocks were mounted. I then removed the rotors and calipers, installed 1988 one ton rotors, put the calipers back on and a proportioning valve and a dual chamber m cylinder in the stock location with a booster and it rides, handles, steers, and stops like a 73 to 85 square body. make sure to right down any V I N or serial number you come across, most frames are numbered on the front. and make sure (most important) that you keep the wheel base the same.

Re: subframe question

can get a 91 1 ton dually frame but not sure on making it work.

also can get a mid 90's 3500 hd.
it has 19.5 wheels and 454ci with 4l80e

Those years have a lot more curves in the frame.

Re: subframe question

Got my hands on a perfect 1980 long bed 3/4 ton frame. Looks like I will do the complete swap instead of the graft after all.

Re: subframe question

plates bolted into place and ready to weld.
I know the plates are overkill but I like to over engineer everything.
