Underdrive pullies (UDP) for S52 M3

[95maxrider]

These underdrive pullies came on my 1998 BMW E36 M3, but I want to run stock-sized pullies, so I removed them. They don't have any markings on them to determine the manufacturer. The pullies are for the power steering, alternator, and water pump. They have some cosmetic wear, but are 100% mechanically sound. Pulley sets are all about $250 new, so I think $150 is fair for an item that doesn't wear out. Price is firm. These probably work on other E36s but I can't offer any guarantees. I'm located in Herndon, VA.

Do you know which alternator this pulley set works on?

I had it on an 80a alternator, not sure if the 140a alternators are different. Do you know?

Is it an OEM Bosch alternator or is it an OEM Valeo? I’m not sure if the 80 or 140 is different but I know the two brands were offered on our cars and require different pulleys

I just went and checked, it's an 80a OEM Valeo.
