I'm replacing the cross-over extention pipe, the little pipe that goes from the cross-over pipe to the wastegate. I replaced the gasket on the side of the removeable flange. The other gasket needs to be replaced (between wastegate and pipe), but I can't find the part number for it. I looked in PET and found part number 944 111 205 04, but it doesn't fit. I have 2 of those here, and are too big. Anyone know which gasket I use?

 

Looks like it should be number 8 which has a different part number than what you posted

good luck,
Rob
