I tried contacting them before but the emails I sent just got bounced back, you might want to try calling them seeing as you are in the US. Failing that give Neil at www.rwracing.co.uk a shout and he will make the sizes you need for you. He had some old stock that he had made previously but otherwise he was going to make them to size for me. Fair price and a good service, email replys can be a little slow (few days) if he is busy though.
