Changing to BBP on 83/4

dont redrill it dont leave much meat on flange best bet is to find a set of non tapered axles from truck are others like b body and have them cut and resplined i payed 100 bucks for truck rear and 200 to have them cut down and resplined and if you going to spend the money to do that look on ebay they have new set of axles with the green bearing instaled for like 300 bucks but then you will still need the brake backing plates and that may cost you another 100 bucks so either way you looking at about 400 bucks to have it done i just went threw all this last weak so good luck
