where can i get a kit to rebuild my rear end in my camaro? it is a posi and i heard some arent rebuildable and how can i tell if it is or not?

 

Pull the differential cover. If it's an Eaton Guvlock, it's most likely not cost effective to rebuild. The Guvlock is identified by the springs and bob-weights that are inside the carrier, whereas the Borg Warner has conventional clutch packs in there.
