Milodon oil pan what is correct gasket to seal it to rear main?

That explains it, it’s a 30935 milodon pan for a 318/340. Darn it. Looks like I’ll be looking for a new to me oil pan and selling this one off.

Didn’t realize it till I tried to install it.
Do yourself a favor and when you get another pan don't buy another milodon. At least not that particular one. I could go on about the problems I've had with mine From brand new. One of the factory Welds leaked right out of the gate. In my a body I had to cut the K member. The driver side header touches it. I had to bang on it to make the oil pump fit. I had to bang on it to make the pickup fit.
