Default Re: 32 B4 rear seal missing

For a good reproduction of the original: Snyder's has them in their offerings: Rear main oil seal B-6335

Another option that I most often use on a B block is the Small Block Chevy (SBC) rear seal modification. Dan McEachern, from California, makes a SBC seal holder that is machined with the block to accurately align it. If you plan to up the oil pressure to the mains, this system will help eliminate leaks. I have used about 8 of the kits in the past 12 years. Order the kit before you send your crankshaft out for grinding as the instructions included with the kit provide the details for the crankshaft grinder.

Good luck with your project.
Good Day!
