I have a BMW E30 1992 convertible and the motor housing drive mechanism has sheared off and bent the drive arms. I desperately need a motor housing from a possibly brocken motor to get mine working again. Have had the part welded back on but as soon as it was connected to the arms it sheared off straight away. If anyone can help me i would be eternally grateful. Love my car so much and hate to have a part of it not working properly.
