I want to do a rear end swap on my 57 shortbox.
The guy before me put a **** rear end in the truck.I want to change it to a GM 10 bolt posi.
By measurement, it lloks like the 1st and 2nd generation camaro or firebird will fit.
I know the F body cars only used 1 or 2 springs, my truck has 7 perside.
I will have to cut the old spring hangers off and weld on some deeper ones, from a truck I guess.

Am I on the right track, what else works

Please help

Paul
