Yes - I'd be interested in a tank as well for my Barracuda. I'd like it to be similar to a first gen mustang, where the the top of the tank is actually the floor of the trunk. Also, with a stailess tank - it's a shame to cover it up with paint. , and the tank is mounted around the perimeter of the top, between the frame rails.
This is a repop steel tank from my Mustang Build, painted with High Build Chassis Saver:
