Thanks Richard, not sure if I have an issue then, I am hoping to take part in some of the speed championships the club do, and neither my strut OR the roll bar have this sticker applied, the Petty struts I have access to, one has a sticker but one doesn't (the one in my garage doesn't) and for Arch/Caterham cars etc to confirm the details they need the original batch number/receipt number? Considering my car is 24 years old as is the equipment I can't get confirmation of that. So like I say, I'm not sure if I have an issue or not? Best ask a question on the right forum I reckon.
