What is the Ford application that has the same size rear main seal for a SBO but is two piece rubber? Putting the 403 back together and the rear main seal and intake gaskets are all that I still need to buy.

I did a search, but couldn't find a thread with a direct answer quickly.
Thanks all!

And boom. Answer in minutes! Thanks a bunch!

olds 307 and 403

I used the 292 Ford Y block seal, it goes in easy. I also used the AMC 252 inline 6 seal, supposedly the AMC 360 is the same without the "ears" on it. It is a tighter fit than the 292 seal. Lube is needed to install, most offset the seal from the cap line and use RTV at the seal ends and a little bit in the cap. Here is some links. One actually as an Olds replacement.

AMC 6 seal, you can see the extra "ears" that need trimmed.
