Sparky1, I'm running a 70's Ford Dana 60 in my '53 3/4.
Has 3.73 gears. Required spring perch relocation, shock mounts transplanted, driveshaft modification, ebrake cable work.
Width is very close to original. In fact I'm running 9 3/4" mag wheels with 31/10.50/16.5 tires. Has the same 8-lug pattern, but the center hub on the Ford rear is too large for the stock chevy wheels. So, not a bolt in , but quite doable. With a granny 4speed I do not miss the 4.56's.
