Does anybody make a LH bedside panel for dentsides with no gas tank holes?

 

Not to my knowledge. Fuel door on full bedside or patch panel with round hole, unless you can find NOS bedside with round hole.

 

Any thoughts on just eliminating the in cab tank, welding that hole shut and adding a rear fuel tank?

 

1973/76 Stylesides have exposed fuel caps, 1977/79's have fuel doors.

What about the highboy? I know it had an in-cab tank, but did it also have a rear tank?

Looking back at the OP's sig, I guess he already has all highboys.

Find someone to MIG in a panel to blank it off I guess.
