The part number given appears to be euro only, but I dont know enough about the part number interchange to say what the difference is. The body looks very similar to most of the US pumps I've seen.
Anyways, here are the details:
The correct pump is on the left. Part # 035 145 155 H Also, the front of the body has AE8 and 123B cast in it. Car is a circa 1982 Audi S1 Quattro. Thank you for any sourcing you can find. We need the pump here by Wed morning (4/3) at the latest.
