Power window motor

need some help. I have a 1980 Lebaron town and country wagon. I keep eating up power window motor gears. I replaced the gear 3 times and keep breaking at the same place. Which is the small gear that runs against the main window plate. I thinking the teeth are bad on the plate. And would like to replace everything. So if any one has one that I can purchase. It for front driver side window. Thanks
