**Gasket or just RTV is the Question**

I use black on the housing side of the gasket on my 8 3/4. Just a skim coat
to cover imperfections. Then used a light skim coating of chassis grease on
the side for the center section. That way if you take it out for any reason.
Change gears like U do for racing and street use. You can reuse it. Had
the one on my car for 3 years. about 6 changes. Works for me.
