Before I pay $90. for a fiber gear I would rummage through every U pull It with 50 miles.....I did find a nice one after going through 2 or 3 old MB's with Webasso motors.
The big PITA is removing the motor while the cable is still in the gears, while you're hanging 1/2 way in the trunk in a bad position. Then you can take off the 3 screws that hold the cover on the motor and see if you have a good gear. One that is still round without any wear on the teeth...

Someone here posted he had a machine shop make him one out of copper in a mold...for like $60. I would do that if I knew of someone.
