OLDS Rear main seal SBO

[rfpowerdude]

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.

Seen 460 seal used on Olds 455 not sure if same as 403.

No, it's different. There is another Ford application that fits the SBO.
