Piece of cake! Everyone talks about taking a older B body 8 3/4 and putting it into a C body. But no one talks about taking an older B body 8 3/4 and installing it in a newer B body. It let me fit the rear rubber in the wells (M50-15"s) with a slight mod and the older B body's are cheap compared to finding one for a newer. If anyone has questions let me know I'll get back as soon as possible.
This isnt the pic for the new rear yet. Ill post it when I get a chance.
