I know this question has probably been asked before but I can't find it. Does anyone know where I can get the teflon buttons to fit into my rear leaf spring on my Mk3 Spitfire? Various suppliers can supply the rubber ones but I'd like teflon/nylon. I can get them from ebay from America for about £30 inc postage but I'm sure there must be a place in England I can get them ! I know I can get teflon rods but I haven't got access to a lathe to work them down. Any help would be greatly appreciated.
