How too Narrow a gas tank!
What are your plans for the rear suspension? Maybe being ignorant here but is the tank/filler on a vert. totally different from a 2 or 4 door?
I ask because on my 63' more door I relocated the springs inboard, moved the wheel wells in 3'' (mini tubed) and narrowed my 8 3/4 and had no probs with my O.E tank. I run 28x12-15 M/T's on 10'' wheels.
Only mod I made was to replace the tank strap J-bolt that hooked to the out side of the frame. I drill a 3/8 hole in the bottom of the rail, welded up a 5/16 nut and use a long 5/16 bolt for the strap. Not sure I even needed to do that but I didn't like it hanging outside the frame.
Also added a 3/8 sender to my O.E. tank. (FYI)
Now I can see you doing that tank mod. for exhaust clearance. My exhaust ends in front of the diff. w/turn downs just for that reason. Didn't want tank heaters.
