Is there much of a difference between Delta brand 5 spoke Dragway type rims and original Dragways? I know that delta centres are welded in whereas the Dragways are bolted. Are the spokes the same size? Is the centre hole the same diameter? I have a set of three delta wheels but it seems easier to find a Dragway than a fourth delta. Chasing a 14 x 7 hq - wb pattern if anyone knows where I can find one....thanks
