[DeTomaso] Driver's side window motor

Either that or they were replaced by a previous owner. Do you KNOW they are stock?

Somewhere on my hard drive I have a good photo comparing the two side by side. The differences are subtle. The stock switches have sharp pointed features while the Bosch switches are more rounded....
