do all protege mirrors swap with eachother? the triangles all look very similar that hook on the exterior, prolly just need to drill new holes. anyone know?

 

do you mean power windows and non power windows?

i changed some non power windows with some better non power windows on my friends car and i cant see why you couldnt swap power to non power

but non power to power would involve wiring and such im pretty sure, but for your awnser to your original question yes they will and are interchangible

 

same three screw pattern for all, no drilling required. If you want to wire up power windows, you need to pull the door harness out of an LX, and supposedly that just plugs right in, although I never got around to doing it on my DX. That and you'd need the power window switch, and off the top of my head you'd be all set
