I did get to the shop in time he had already broke down the 4.10 case I left with him but hadn't started to set up 529's . Which is good and a pain all at once . the 4.10's were the only other complete set up I had. So when I take him the abs diff my truck will be un movable. Don't drive it enough to need it but don't want it stuck in my shop either. But at least I wont have to delete the abs or have the stupid dash light on . thanks guys
