I hinged mine from the 2x2 crossmember just outboard of the 3/4" pedal box supports. I then used a small (Don't know what to call it) latch to hold it up. When I need to get to the box, I just turn the latch that is screwed to the 3/4 tube, and the fuse box swings down for easy access. The latch is something I found in my garage, that was left here from the '50s. It looks like something that would be used to hold a screen w/frame in an old wood storm door. It looks like a wing nut but isn't threaded in the center. It works great. I could not get my fusebox inbetween the 3/4" supports. My harness didn't have enough slack to let me swing it down. That is why I went to the outboard side.
