I have a stock rear main seal that leaks oil urrrgghhh!! , 440 source main caps, the main caps studs didnt clear the stock seal retainer,, massaging was necessary. How well do these newer billet rear main seal retainers clear after market main caps/ and or studs ??,, in addition are folks happy how well the new billet piece seals.. thought about purchasing the Mancini racing billet ??

Thanks again moparts family
