So after my accident a few years back the repainted rear door never matched the rest of my car, so recently i found a guy parting out a silver corolla with power windows, locks. Will it be hard to swap my manual windows cover with his power everything? I'm also swapping the windows because mine is tinted but ill still need to get the little small window spot tinted later on. In terms of color match will it be spot on even though the car is 2 years newer? I'm assuming its the weather wear that makes it so hard to color match. And also, if the car has the little moulding thing on it, if i take that off will it leave a big pale mark underneath? or will there be holes underneath it?
