If you use a new reproduction gas tank the holes to mount the new tank need to be re drilled. ( I think 5/8" forward ) This will let the fill hose go through the side of truck so it will connect to fill tube, still have my old tank if you need one. I would purchase a new one because of rust and new one has a baffle. New tank will also have to be painted. Need to think about your gas sending unit and gas gauge. Your work looks great!!!!!!!!!!!!
