    Autozone sells two Felpro rear main seals. One is rubber and is $10 and the other is Teflon and is $20 and special order

    If the Teflon one better to get? I want to do this once and not have it leak anytime soon.

    If you have a stick car and you drive it, don't plan on putting in a rear main seal once and forgetting about it- they go through them like dirty socks. The teflon one is better. I don't know that it's ten dollars better, but WTF? It's only $10! You can look at it two ways: either, "Oh my God! It's 100% more expensive!"; or, "after spending $450 on this clutch job, what's another ten bucks?" Your call- I splurged and got the one that sounded cool.

    The teflon will take the heat better and not be prone to cracking like the rubber does.

    If properly installed they will last for a long time....
