'65 F-100 gas tank is behind the seat. There is a hump under the seat all the way across, so no under the seat mounting either. Dash is steel. Doors are ALL steel, including access panels. There is NO radio 'kit" made for it(jigsaw and plenty of blades and a steady hand). Came with ONE speaker in the center of the dash. All speaker placements have to be fabricated. There is no insulation or sound deadening of any type, tin-can acoustics. Basically, there is not ONE component that can be installed without fabrication. Any GOOD aspects to this vehicle?
