My thinking was that the feet are basically a T and mount horizontal, left to right, on the crossbar. The upright of the T has a hole in it, it fits into a slot in the bottom of the leg and pin runs thru. By cutting the legs and machining new slots and pin holes, then bending the feet straight up into the new slots I think they will pivot. It would mount across the bar right above the tramp track. The slots are wider than the upright and theres some play in the pins. Maybe I'm dead wrong thinking this will work? I haven't cut anything yet! It seems feasible looking at it, the crossbar isn't all that curved thru this much area, maybe 1" rise, but haven't measured. What do you think, will it work?
