The Ford Barn

Gentlemen, Hoping someone out there can provide me with appropriate guidance.

I have a VG 1942 Ford block all tested and good to go. The original crankshaft was badly scored and I was advised to retrofit an 8BA crankshaft and rods to replace my rotating assembly. I managed to locate a stock sized 8BA crankshaft which has been ground and balanced (minus .010"). Notably, the 8BA crankshaft has a single oil slinger whereas my 1942 crankshaft has 2 rear oil slingers

A couple of questions:
1. With the 42 Ford block, which seal retainer(s) do I need? I am advised I need 91A-6335 (Upper seal) which will accept the later 8BA seal. Is this correct?

2. What happens with the lower seal? Does this need to be changed? if so what do I need here?

Thanks for your help

David
