That was my next plan of attack, figured I would weld the seam then throw a strip down the center to fill the gap that is there. I was also thinking it would be worth adding supports on the underside of the truck.
Being that it has a 216 in it and gears that could pull stumps, 65 is not in its future..... I wish it was but the dually setup stinks for me, but the cab is in such great shape I figured I would build it just the same.
