Hey guys,

Finding a reliable rebuilder for these seems pretty hard to come by now-a-days. Wondering who you guys recommend for rebuilding / adding a LSD? It took me a few months to find a good core, so I have a core I can ship out, I just need to find the rebuilder.

*added picture for my car's current state :(

It's not too hard to rebuild it yourself. The only required specialty tool you need is a hydraulic press to take the gears off the stack. That's only required if you're replacing the synchronizers though.

How deep of a rebuild are you looking for? Simply swapping to an LSD requires nothing more than hand tools and gasket maker to reseal the case.

I can help you along the way just need to know exactly what you're going for.
