There are two different P/N for Eaton type of an outside mirror drive motor. These are 67137187261 and 67137187262. I'm seeking help in understanding the difference between the two parts that hide under these part numbers. I already made a mistake once and bought a wrong non-Eaton drive motor Now I want to avoid making a similar mistake as there are two seemingly indistinguishable options. Any recommendations and hints will be appreciated.

I looked at RealOEM.com and it is not helpful around telling the difference
