I can't help with parts, but I suggest that (with new rubber) when you get another gear or another regulator, be sure the parts are aligned correctly to allow the vent window to close as easily as possible, then apply some rubber lubricant to the contact areas of the glass and frame, and gently close the window by cranking the handle and applying light hand pressure to the glass to help it close snugly.
Then leave it closed for a few days so the rubber can take a set. That should avoid over stressing the gear, if it is meshing properly and lubricated properly.

New rubber parts like vent window rubber and door and trunk gaskets often need a few days to conform to the gaps they have to seal.

This is best done in warm weather or a heated garage, if one is available. After a few days, some re-adjustment may be needed, so I'd avoid replacing upholstery until the vent window works satisfactorily. I like the crank-type vent windows, but a lot of them are stripped. If the vent window leaks and whistles when closed, it may need further adjustment. Forcing the window shut with the crank is likely to give trouble.
