    This has probably been discussed here before....does anyone have any info on Fel Pro rear main seals?

    I show 2 part numbers - #2947 is Fluoroelastomer and #BS 40240 is rubber...

    Seems that I have used the 2947 in the past....but need to know which one works best in nitro applications...

    There is also a Cometic part number at O'Reilly....

    Just looking to have a few spare rear main seals on hand....
