I just went through this with my '87.

First off, you do not want to put metal gears in the lifter housings. The plastic gears are commonly referred to as being "sacrificial" in that the plastic gears fail to protect the system from a more catastrophic failure.

There are two main causes for these gears to fail: Either the micor-switches are out of adjustment, or the slip clutch is out of adjustment.

To get the system set up properly, go here: http://www.pelicanparts.com/techarti...44_sunroof.htm

Print the article, and then read it several times until you understand how the system works.

I can't find the metal gears in any of my catalogs.

I _know_ that someone sold them at one point (as a replacement for the plastic gears), and it was either Tweeks, Performance Products, or Automotion (which merged with Performance).

I had a period of time where I frequently broke the plastic gears. But once everything is adjusted properly, they can last for years.

The pre-86 cars have a metal sunroof gear but it's a different system design and not interchangeable with the later system.
If the arms and the slip clutch are adjusted correctly you should not have a problem with the gears.

Cool. If the slip clutch adjustment works (I'll try it Sunday), you guys will be my heroes!
Rennlist is definitely worth the $18.

Anyone have pictures of those cams for the later models. I have an 87 and I want to make sure that I'm adjusting the stop cams correctly. They are located near the motor correct?

Adjusting the slip clutch is done by simply tightening or loosening the inner, smaller nut that is "inside" the huge nut that is used to manually raise/lower the roof. I do it by "feel", as I do not have a torque wrench.

I don't have pictures, but it's the position of the microswitches that is adjusted. There are two little Philips head screws through the ganged switches; loosen them and slide the switches forward or back. I recently found my ganged microswitches loose. Symptoms were no movement in key position I and arms retracting too far in position II.

The screws are easier to get to if you detach the sunroof motor/switch/relays assembly from its mounts (3 10mm nuts, IIRC). The nuts on these little screws are something weird like 5.5mm. Best just to hold them with needlenose pliers, but I guess a 7/32" wrench would work if you have such an animal.
