rear main oil seal?help?

[ChrisEvans]

I have an R302 block & a bryant billet crank(nascar take out)-my problem is-a standard 302 rear main oil seal wont work?I measured the end of the bryant crank-3.750(351) & I measured my old(broken)302 crank-3.625...obviously I can't just use a 351 seal(wont fit in my R302 block)...what to do.......turn down the end of the Bryant crank(to 3.625)or does someone make a special seal for it? Anyone know?Thanks for any help!!:)

Chris are you looking for a double lipped seal for use with a vac pump?

No-I don't have a vac pump. I had a local place just turn down the end today.....thanks for the reply!
