Well, ive got my royal purple differential fluid and need to change whats in it soon. I just got my brand new diff cover to my 8.8" and the gasket in the mail yesterday. It was only $15 for it and its fully stock OEM blasted parts. So, now that I have the new cover, im taking it to get black chromed at the powdercoat shop. Its gonna cost $65 to get it media blasted and black chrome plated. Once I take it in it will probably ake a week to get it back and then off to change the fluid and cover!
