Next I herculiner'ed the entire underside. That should seal it up for a long time. It stuck as well to the wood as it did the metal.
In the second picture, you can see that I've moved the gas filler pipe from the passenger side to the driver's side. I used the stock S10 filler pipe, bent a little more bend into it, and mounted it about 7" forward of the old one. This gives me enough room to do a double 90 degree turn into the tank. (in a previous post, I said I had a 13 gallon tank. Turns out I have the larger 19 gallon model).
The fourth picture shows the filler pipe mounted on the outside skin. I used rivet-nuts to mount both the filler pipe and the new billet aluminum door. I'm happy with the way it turned out.
