Lowered the spare wheel - figured it out, bloody good job I did, never have got that spare off at the side of the road. Plastic wing nut that holds the 'bracket' to the wheel was stuck fast and now its bust, had to muller it to get it off. Wheel was even rusted to the bracket. All cleaned off and greased, but what size nut do I need to replace the 'plastic wing nut' that is no more ?
