Me and my buddy spent all weekend working on changing his diff on his 88 hardtop, and when we got it all put back together, we of course went to go for a ride to celebrate our success, well when he put it in first, the diff went "boom". upon further inspection and much disapointment, we realizes that those studs that the arms of the diff go up were stripped by the nut under the pressure. well now we cant get another nut on the stud. What to do? suggestions please, we have already touched on the possibility of welding, so any other ideas besides that. Thanks in advance.
