Ask him why he's selling it.

 

he got a engine swap

You don't NEED his pan, but if it already has the return flange in it, it'll save you the trouble of tapping yours, and you can just swap his pan on..............

the oil pan has a nipple screwed into it and connects to a stainless steel braided return line

i take it thats the return flange?

 

Yes
