Ok what can we help with? JR rear?

Do remember ANY 10 bolt 8.5 rear into any GM with out a original 8.5 rear will ALWAYS need a driveshaft shortening.

Next sometimes adjustable upper control arms are needed for pinion angle correctness- we sell our rears with double adjustable upper control arms as we use a 1973-1977 A-body 10 bolt 8.5 center mated with the original 7.5 10 bolt tubes. The lower control arm mounts will be in the original location and width and the spring perches over the center of the axle housing tube.
