Nice work! I had to shop around for motor mounts as OEM were crazy money and the better brands were out of stock at a lot of places.

I'll be interested to hear what you find inside that diff, pics please. Mine weeps the slightest bit of oil from the lower bolts holding the halves together, but I couldn't torque them at all. I did a half hearted look for gaskets and any other internals for the diff and couldn't find anything on the internet either. I guess if it ever comes to it and I need to address any heavy leaking I'll need to make a gasket.

One more note, I had a tough time pulling the breather tube out of the top of the diff. The flexible rubber bit that went into the diff was nowhere near flexible any longer and it shattered. I ended up having to make a new connecting piece out of larger vacuum tubing. A lot more wd40 and patience may have helped.
