Jay - first fit the centre T bar into the spare. Use a folded towel to hold the wheel up against the cobra. Then fit the side fasteners, but keep two towels covering the rear deck, as the rack will try to bounce on it. When all is attached just tighten it up. The T bar is usually a pig to start as it goes in at a strange angle.
