I was trying to be prepared in case one or more broke...they have a strange angle on the legs on the back side of the door panel.
The new ones appear to have the holes very close to the holes in the panel but that does not mean they will actually match up.
I had no one to help me and I was afraid to drop the window down because I knew it would come out of the tracks and I figured I would end up breaking it if I tried to pull it out. Maybe if I knew what I was doing, it would have been okay. When I did the outside one, one of the screws on the end was missing. I found it down in the door. But when I put the new one in, I could not get one of the middle screws back in so I ended up with three out of four going back in. If I had some one with small fingers, or a magnetic right angle screw driver shaped like an allen key, I probably could have got it started. The outer one lined up perfectly with the factory locations. These big doors and windows create their own problems.
