I have a '59 Apache panel. I had a bad bottom door hinge on the passenger side. In taking it apart, I removed the door and both upper and lower hinges. This was partially for clean-up and primer while I had it apart. The upper hinge had a bolt in the back (foreward most)part of the hinge. When I removed the bolt, there was a square nut on the backside that fell down on to the floor. My problem is that I can't get the nut back up there to put the bolt back in. I can't get to it from the bottom where it fell out and I can't get to it from under the hood. My arm is too big to reach back there. Do I have to remove the fender in order to get to the back side of the bolt? I think I must be missing something? Thanks....
