Hi Nick - I've done this on an E36 coupe too and I found that the seals were the same as the rest of the E32, E34 and E36 models.

The two different part numbers are because the early cars (E34 pre 09/91) have metal door handles and the later ones have plastic door handles. The shape of the outside trim part is exactly the same and they are interchangeable. I think the E32 all have metal and the E36 all have plastic.
