1981 Window motors and a regulator

Post by Tazzarti » Wed Nov 01, 2017 12:45 pm


Im looking for the front two window motors, as well as the front right window regulator from the old style 633 (1981 here). The part numbers are as follows:

Front left motor 51331369249 superseded by 51331375247
front right motor 51331369250 superseded by 51331375248
front right regulator 51331921506

I will probably need rear motors too but thats not as big a priority for me. I am attempting to rebuild the motors, it seems the bimetal switches are just dead, but the one regulator is broken so I need that.
