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
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. |
