I have a 68 camaro w 10 bolt rear end differential, posi traction unit with bad carrier, w 3.10 ratio, 8.5 in ring gear, 30 spline non c-clip axles, will the eaton 19559-010 limited slip carrier work in this Axle housing?

Asked by Shade tree mechanic from Tuscaloosa, al on

Hello All of the Chevy 10 bolt rear axles had C-Clips so there has been some work done to yours. The 68 Camaro would of had an 8.2 10 bolt with 28 spline axles. So yours being an 8.5 with 30 spline it has to be an updated custom axle. The unit you asked will work with or without C-Clip axles.
