Milodon Oil pan fitment

I bought mine used and I spent at least 2.5 hours trying to get it to fit and gave up and went with a stock pan. I emailed him about it and he says "Oh yeah,I forgot to tell you that you have to notch the k frame" lol. I wasn't going to hack my k frame to use it. Tryu posting the part# and fitment issue and see what others have come up with.
