I was told this at one time, by AndyZ28 (the guy that makes the replacement 3rd gen door hinges):
"Contact Lon Salgren at Top Down Solutions Inc.
[email protected] 1-626-369-0040 He is the ONLY one that I can suggest. He has a wealth of information and parts for the hatch pull down motors."
I also found this info:
