I am looking for a Sun Roof Motor to buy.
Any Information for the Part Numbers For this car.
Have you contacted your Chevy dealer to find that part number?
Parts for a 40 tear old vehicle will be very difficult to find. Try looking for vintage Chevy and Mailbu sites for new old stock parts. Or look for a rebuilder for your original motor. There may be a reproduction part made and available from NPD or LMC.
Good Luck.
