Well, I finally got the oil filler and nut off of my '74 Beetle. It was leaking a little oil and of course, was very difficult to get off. I grinded off the tin and then used a pipe wrench and vice-grip to get the nut off. Actually, the nut broke but that's okay.
I have a replacement nut and oil filler but no washer. I believe the original was a paper gasket? And I notice that California Import Parts sells what seems to be a cork gasket. The link is below with a picture of the cork gasket.
Thanks for any feedback.
