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

Oh you got me started now! LOL well Summit credited me a discount and milodon said they would replace it. It's still wears the J-B Weld covered by the right stuff from Permatex. Do I want to chance sending it to them and telling me it wasn't their fault blah blah blah and sending it back and me having my car down for a month waiting for them? I'm not willing to take that chance...
