I have a 1955.2 3800 that's got what I assume to be a custom 8' X 10' flat dump bed with 12" wooden sides. When I got it it wasn't derivable. I really want to get it road worthy so I can enjoy it while I'm working on it and not lose interest. To make that happen first I fixed the breaks so I'll be able to stop when I get it on the road. That was a big step to me. Then I got the lights working. Now I need to make sure I can see. The truck didn't have any mirrors at all when I got it. It's too rusted above the windshield to have a rear-view mirror right now so that's not an option yet. The drivers side door I put a mirror on because it had the 3 mounting holes for a side mirror but that door has been replaced sometime in it's life. I know this because it's ORANGE and the rest of the truck is green. I think the orange door must have come off a smaller truck because the passenger door doesn't have mounting holes. Did 3800s have mirrors originally? If so how did they mount?
I have two problems I'm looking for help with.

1.) The passenger door doesn't have mounting holes for a mirror. - how do I mount a mirror?

2.) The drivers door mirror is too close to see past the wooden bed rails so this mirror didn't do me much good.- how can I adjust it or change it so I can use it?
