Don't Do It STOP Scott, Step away from the Gov-Lock piece of junk! (see:boat anchor) :spank: Anyone on the board that knows differentials will agree with me here. They are O.K. for a low budget pick-up truck Posi but are crap otherwise. Several previous threads on these. There are 30 splines on the side gears anyway. George or someone can put up the "Link" for you. Sorry, I'm not that computer literate o No: or I would...Tim
