Northy you may be one of the lucky ones. I bought out an entire importer years ago of all his stock ( a mountain of stuff) and I got 3 pairs of these items nib. I havent seen many around. I sold 2 Bosscat works cars fitted with these but you may be the first person Ive heard of that has them too. It will be interesting to see if there are many people out there that have them.
