Problems with oil pan clearance.... I know, I´ve been warned....

.... I found two 971 oil pans on eBay. But to me they look different!.............

Looks to me the black one is a higher capacity sump with the appropriate oil pickup. The other is a "stock" replacement I do believe.

The second one is the correct one, but that price is outrageous. I would offer $100 tops, and if he says no keep looking.
