8 3/4 B to A swap

I believe the housing is 3-1/4" too wide if my information is correct. The spring perches will have to be moved in to 43" center to center. Cost is area dependent. Costs me about $250 to get a housing and axles shortened but I've heard guys in other states say it's up to $400 where they live. Due to having to buy different axles (you can't shorten B-body axles to a-body length because their tapered down right after the splines) it'll most likely cost more to have it done than buying an a-body setup.

Not sure on the parking brake cables but you will have the change the driveshaft if the rear in the car now is anything other than an 8-3/4
