Universal Aluminum Access Door, 6 x 6 Inch, Black

I relocated a fuel cell between the frame rails, underneath the truck bed of a 46 Ford rat rod. To make the fuel cap accessible, there had to be an access door. I cut a square (6""x6"") opening into the truck bed and mounted the access door with the frame (8""x8"") over it. I used pop rivets to attach the hinge to the door and to attach the quarter turn fastener to the door. Same for spring. The entire installation took less than one hour. All pieces fit well and pre-drilled holes aligned.
