I think you were the Justin being referenced.
The issue isn't the size of the top tube, it is the top motor mount. The mount adds about 1/4-1/2" on either side of the tube.50gary said:How wide is the tank tunnel, and how wide is the top tube? Perhaps you could cut out the top tube and replace it with a narrow width but deep section rectangular tube to maintain strength. Might work with the right sizes and wall thickness. Oval tubing is available if you search.
