Well after a couple of years of gathering parts the transplant has finally started. Took out the 235/3 speed and going with 250/200r4 combo. A fellow Hamber dropped by and was a big help(Thanks Eli). Tried a differential from an Olds Bravada with disc brakes and it looks like calipers are not gonna clear the frame. Good thing I hadn't scrounged all the other brake hardware. Anyways no turning back now. Also, if use can be made of the stuff I am pulling out shoot me a PM.
