I had to cut-down the passenger-side wind window just like the driver's side but the cast housing
for the gear-drive on the vent window crank was broken, allowing the worm gear to push itself
out of mesh whenever it was cranked.
Thoughts of just putting it in, inoperative, to get closer to completion crossed my mind
but they also didn't sit well and went by the wayside as I tried to come up with a fix.
Epoxying everything back together might hold, and then again it might not.
A better fix was to lengthen the rear backing plate, having it grab around the side to
keep the worm gear in mesh with the drive and also have it wrap around the bottom to hold the
broken housing together. Then drill out the top rivet and replace it with a bolt.
Cinching-down the bolt in the top rivet hole applies clamping forces to pull the rear support
bushing close to the drive and and pulls everything tight around the bottom at the same time.
Everything pulled right into place with the tightening of just the one bolt.
More importantly it stayed there while in operation. I can comfortably put this thing back
inside the door without having to worry about pulling it back apart later.
