I just remembered, u can use a B-body 8.75 rear from like a 67 to 70 I think. Some one help me out:( u will have to move the the spring perches inward like 1 inch each side... that's it. I put one in my 80 Volar'e wagon. I had 15x8.5 wheels, and fat tires. I still had lots of clearance. The later 70's B-body rears are way to wide.
