C30 230ci Rear Main Seal - Fel Pro part wrong?

[divideoverflow]

Hello! Started to tackle the rear main seal and oil pump replacement today in my 65 C30, and had a learning experience :-)
We tried to get the oil pan out without jacking up the engine... which did not work. So we undid the engine mounts, clutch linkage, trans mounts, and then got it up high enough to put a 2x4 under each engine mount attachment location (upper and lower). That gave us enough clearance to get the pan out.

Question regarding the rear main seal itself. The one that advanceauto sent me looks nothing like the one I pulled out. It looks like it is only half as wide, and doesn't have a center groove. I'm not sure if it was a part# mistake, or if Fel pro just makes the wrong part for this thing?

I ordered Felpro Rear Main Seal Set, Part No. BS 13241, which claims to be a perfect fit, and the picture looks like what is in the service manual I have (with the wings):


However, it is nothing like what is in there.
Original Seal:



New Seal:



There was no place for the "wings" to go at the rear main cap, and this would only fill one of the grooves in the main cap... not straddle the center ring of the cap like the original does.

So, is this engine a different year that wouldn't accept the "wing" style rear main seal? I'm afraid to order the "performance" version of the seal from Fel Pro, since I can't tell from the pictures if it is half-width like this one is.

Any help here? Am I missing something?
