Hi all,

The driver's window on my 1988 760 does not go to the top and never
has... it gets to within about 1/4 to 1/8 of an inch and then the
motor starts skipping (buh-buh-buh-buh) and it won't go any higher.

I took the door panel off and discovered that the semicircular metal
gear that the motor engages has had the last 4-5 teeth stripped off.

As I doubt there is any way to repair that stripped gear I'd like to
replace it but I haven't been able to find anything on eBay except the
whole window regulator. I don't know of any convenient wreckers
(there's an overpriced one 90 minutes away where they do the pulling)
so I'm trying to find another solution.

My questions:
1. Can this gear exist separately or be removed from the rest of the
regulator or is it stamped into place?
2. Can the regulator from the rear door either yield this part or the
entire regulator in a swap?
3. Can the regulator (or this part) be substituted from another
vehicle (the 740 seems so similar to the 760)?

Thanks,
blurp
