You will see the track and the cleats...12-18 inch track on each side of the crossbar will give you the barberhauler effect and would clean up the tramp nicely. I dont know if you want the swivel or fixed though? I would think swivel.
Im talking about the series 19 c-track stuff thats in the secon picture.
