Here is a piece of sheet metal I found buried in the bed of the truck. If you put it on the side of the truck it is curved to the same angles as the fuel filler hole on the passenger side of the cab. Since I'm planning on an underbed gas tank in the finished truck(not the one pictured, by the way, that covering the old filler hole for the cab will be necessary. I'm thinking of welding the curved sheet metal to the inside of the cab where it will be hidden by the interior liner behind the seat, to use as a backing plate. Then I can weld in a oval piece to match the existing hole, grind it smooth and Bob's your uncle!



I'm also trying to figure out the best aproach to beefing up this seem above the rear window. The interior weld is rusted and crumbling away. I figure I'll grind the rust away and see if I can weld it also from the inside because again it will be hidden from sight, by the head liner.


Since this welding stuff is all new to me I figure I'd ask if this approach makes sense and will work!
