main bearing caps

[Don Cape Cod]

I'm in need of a standard rear bearing cap. When I was a young man, you used to be able to find them in automotive specialty stores. I think it was a Pep Boy's in Parkersburg, WVA. Probably back in the late 50's. There were mains and rear caps of various oversize. I still have Prussian Blue and a Babbitt "scraper" which I've used every 10 years or so to fit them properly. That might have been a Western Auto store. Back then the Blennerhasset Hotel had a working fireplace in the lobby.

Is there a vendor or individual that can supply me with a "standard" rear main cap, either new cast or good used? Near 1.620.
