Everything is apart , cleaned up and ready to install

Bought the billet rear main seal retainer kit from Mancini racing

Should I use the supplied rear main seal from Mancini racing or I also bought the Superformance rear main seal when I purchased there oil pan gaskets , thinking of using there rear main seal with the Mancini billet retainer

Then obviously using the double side black rubber o rings supplied with Mancini kit

Anyways , any other tricks used installing this Mancini racing billet retainer before I button everything up today

Superformance rear main seal work with the Mancini racing billet retainer ?
