That is REALLY a beautiful and clean restofication of your truck. The only thing that scares me about where you have your gas tank is its exposure to the Pinto-effect if some car rearends you and slides under your truck, rupturing your tank.
I have a long-bed, so I have room for two full size gas tanks in front of the differential. Of course, in my case, I think I'd better design a driveshaft loop to protect the tank from rupturing if the u-joint should ever break.
