AYA now has their own USA sales office, or they did about six months ago. The office has been set up within an existing sporting goods firm, which I've forgotten the name of. I ordered a toplever spring from them for my old model 51 and I had it within a couple weeks. My computer died since that order and I don't have the website, but if memory serves, it was something like ayausa.com. A google search will find it. Good luck.
