I have a steel 3.17 gallon XT350 tank in good shape I'd be willing to trade plus some cash for your Clarke tank. That would give you almost 1/2 gallon more than the Clarke TW tank. The bars with no risers barely touch at full lock, and I have the tank installed all the way forward. The tank does have 2 shallow dents on the right side, but they aren't noticeable and the tank is clean as a whistle inside. I can provide pictures if you like. PM me if you want to talk turkey.
