I bought a 960X400X400 alloy tool box to fit on A frame and found the jockey wheel winder would not clear ...after a bit of head scratching and contemplating surgery (for me as well) I came up with simply turning around the gas bottle holder which placed the band clamps to the rear and allowed a bit of fudging ...and it is al good. It seems obvious in retrospect but hopefully this might help others.see pic
