[50 Chevy LS3]

I used the Nolimit, aluminum, tank in my 1950 project. It is similar to the steel one, with frame tabs described above, except that the tabs are one-piece, straight welded aluminum. They conform to neither the frame or the rear crossmember. Nolimit instructs you to form wooden blocks to allow mounting. Maybe a good enough solution, but, I was less than impressed. I instead mounted mine, inside the channel frame rails on a self fabricated "ledge". On final assembly, a thin rubber pad will be used between this ledge and the tank. Mounting higher in the frame keeps the tank less visible from the rear. Caution must be taken, however, as mine is very close to where the bed floor will be. Less than 1/2" from the wooden bed floor.
