Daryl, if you're not stuck for space (yes i know you're cleaning your garage out) I'd be inclined to do as Mack says and keep hold of it as there is always someone looking to revert back to stock prior to selling, it might get you a few quid or part payment to something that you want. But, if space is at a premium I'd either put it on fleabay or offer it to someone for free on this site as long as they collect. Or give it a couple of weeks then scrap it.
