Car has remote adjust driver mirror. Im in the middle of restoration and have the door off the car, window out and cant for the life of me figure how to get the mirror off. There are 2 bolts coming through the door from the mirror. The rear most one is easy and you can put a socket straight on. The front one , just ahead of where the remote cable comes through, is hidden inside the inner door metal. I see VERY little room to get to the nut. Any input ?
