Rear main seal Sup tech, i narrowed down a leak and im debating on buying from http://www.gmpartsdirect.com/results.cfm,part number 12639250 before i buy i have a question. Do you guys know if this seal is made of teflon?, cause if it is then im assuming its recommended to be installed bone dry. As for the complete housing, would i just install it as it comes, meaning when i remove my (old) cover, gasket, seal etc. do i just do a straightforward install with this new one?
Feedback would we appreciated

Yes, install the whole setup, minus the white support.
It comes with light grease applied to the inner edge of the seal.
I don't know if the seal is made of Teflon.
If you haven't done a rear seal before, it is important to exactly center the seal to the crank hub.
