A?C Part number question

[Ral]

My car's currently in the shop getting a new blower motor, but I've run into a snag. I ordered a part, p/n 64 11 1 373 766, which Realoem lists as a Blower Motor for E30's and Z3's. However, it has a much smaller diameter than the old part, and a different part number from what the shop looked up, which was 64 11 1 466 014, and shows up on RealOEM as the same thing. Anyone have any inputs? Were there two different types of blower motors for these cars?

Car's an '89 M3

64-11-1-466-014-M6 - All E30s until 5/89. According to Pelican Parts this is the only one available and is produced by Behr. There is an -015 genuine BMW but that is NLA.

Hmm. wonder why RealOEM had both listed?

Those are the cars that came without a/c and had a cabin air filter right?

I've never seen one before myself. My Canadian car has a/c and a regular blower motor and blower resistors.
