help regarding foot pack, fitting kit and roof bars

[shifty]

Hi, I have some extra wide thule roof bars and would like to fit them to my 2006 berlingo using a foot pack that allows the bars to pass past the fitting point. This would mean that they would fit by way of clamping around the bar rather than from just underneath as per the rapid fit system. Does anyone know the thule part numbers for a foot pack and fitting kit to allow me to do this even if they are no longer currently available, perhaps I can get them off ebay or somewhere. My intention is to carry an open canoe and narrow top box together ?
