95 Caprice parts car has a complete disc brake rearend, would like to know if it will fit into my 79 BU. I would guess that I would need new uppers/new rims(back spacing) and shorten the drive shaft. Any other concerns about the swap that I should know of? They have 28/30 spline axles right? Don't know what gear it has or if it has posi but if it was cheap enough, the swap from a 7.5 to an 8.5 w/disc would be worth it(if it is not a HUGH pain the the rear)no pun intended :lol:
