I used a 67-69 camaro tank (18 gal)mounted behind the axle. Had to move the rear cross member back and then reinforce the rear spring mounting by boxing that area of the frame. I am happy with the results.
I think ole Popcorn has an extra one of these tanks unless he used it as a sled or parts washer. Drop him a line and say "GO ASTROS" - he loves that.
