Anybody have a input for who sells the best non
leaking retainer and seal kit for a RB

coro500net,
There are several good rear main seal kits out there. The Mopar Perf. one and the INDY one are both good. The trick is in how you install them. If you call and order one of the retainer kits from us we can give you some tips on installing it so it won't leak.

Thanks for the input and I will be contacting you.
3rd times the charm Im hoping.
Im 99% sure it is the problem.
The machine shop that built the motor has replaced
it twice(so he said),he used the factory cap the first time and then used the MP billet cap,so now it is time for me to do it myself.

I got mine from dvorakmachine.com great quality check out his web site
