Backstory. Bought my 2001 Audi A4 1.8T (AWM) Quattro non running. Found they had melted 3 of the 4 pistons. Sourced a used AWM motor and commenced the swap. Did timing belt, water pump, tensioner, etc while the new motor was out. Get ready to drop it in and realized I didn't pick up a new turbo to cat exhaust gasket. Order one from Napa (31390) and it's not the right one even though it was listed for the AWM. Order another one from Advance (31611) and it's not the right one either. Can someone tell me what the part number is for this gasket? Advance is ordering another gasket (61171) to check it's fitment. This is the last part I need to drop this motor in and start hooking everything back up.
