Vintage NOS GM in the original box. Delco power window motor part number 5045665. This number replaced lots of the 1960's and early 1970's part numbers. It has been bench tested and works fine in both directions. The original box is rough. The motor is fine. $175.00, includes safe insured 48 state shipping. PM me if interested.

 

 

Just a thought. It has the mid-late 1970's style plug and there is a 75 stamped in the location I've seen date stamps before. I'm not an expert, but suspect this was originally made as a replacement for a 1975.
