I have a 87 300sdl, with a drivers side window that will only go up and down if I push the window (by hand) down about 4 inches. Then the window will function normally. So I take off the door liner and find out that the tooth of the gear is stripped. So that explains the problem. It looks like the motor is working just fine. But the gear that attaches to the motor has grinded away its teeth. So I’m not needing a complete motor. Just the gear. So here is the problem I’m facing.

What regulator do I need to purchase for this specific make and model. Is there a brand that will last longer, because I don't want to have this problem again.

I’ve checked around with local junk yards and it seems like the 86-87 years are harder to find.
