I had a custom aluminum tank for my Cheetah project built to my specs by RCI in Tyler, TX (RCIracing.com). I worked with Wayne Wilson. ... I started by selecting one of their stock tanks to identify the fittings I wanted, and then told them the dimensions I wanted. Note that they aren't receptive to complicated designs. If you can get by with something with six flat sides. they can work with angled joints and trapezoid shaped end pieces. The cost was not much more than a stock tank.
