The gerotor oil pump is what came from the factory on the 1957-1964 Y engines.  If the engine has been rebuilt sometime since then, the oil pump could have easily been replaced with a spur gear pump.  But the oil pump gland nut and rubber seal are the same for both styles of pumps.

If you have trouble finding those parts, I have the gland nuts and seals as extras.  If you’ll send me your mailing address, I’ll drop one of each in the mail for you.  My email address can be found at my website under the ‘Contact Us’ tab at  www.eatonbalancing.com  .

Hey Ted!
Thanks so much for the reply.   I called my local parts store (O'Riley's) and they had no access to either of those parts.  Their suggestion was a junkyard.  Which of course, there are none around me.
I'll shoot you an email from your website.

Thanks again!
