I also used a file to adjust the camlock fixture so it will fit better. When I attempted to make the camlock work with the map box clecoed to the instrument panel it took an extreme effort to lock the map box door. Now that I have filed the fixed part of the lock it should work just fine. If not I can always purchase another camlock and work on it until it fits properly.
This afternoon I riveted the map box to the instrument panel. It all went together very well. I used flush blind rivets where it was not possible to use the rivet squeezer All of the rivets set very nicely. I will use some Bondo to fill the holes in the blind rivets before I paint the right instrument panel. Next week I will begin to work on the center section of the instrument panel and make an effort to paint them.
