about six months ago i had to replace the gas tank in son n laws 69 mustang. i also had to rebuild the flange area of the trunk, because as most of you know the tank is the trunk floor & the tank sets on the flanges in the tank well. the tank comes with holes for the fasteners already in the flanges. it looks like with trimming the frame rails back then the tank could "slide" into the frame rails & then nut & bolt to rail. that way you wouldn't need the retaining straps. with a little rubber insulation under the flange & a rear filler this looks like the best setup to me. wadda yall think?
