I called Benchmade last week and they still have back-spacers for 970ST, made about 15 years ago. I've found their turn around time to be very good. I've had Axis locking knives since a pre-production 710, back in the 90s when they used ATS-34. Since then I've flicked, waved, and abused several Axis lock knives and never had a spring issue what so ever. Oh, and they sell new blades for $25. Good luck finding that else-where.
I've had Spyderco tell me to retire my knife because they could fix it as it was discontinued.
