I have used round pipe ( 1 5/8" .083 molly) on square frames where your seat support is required between the inner and outer frame rails to make a lower perch. This will require you to put the sheet metal on the outside or bottom of the frame like a belly pan, which is legal. You must use .024 steel min thickness, welded in place.That will net you possibly 2 3/8" lower starting point for your seat bottom.
