heres a bigger picture:
just going from the picture, it looks to me like those holes are way too close to the old one, i don't think a helicoil or insert will help you out ...
best bet would be a complete remount forward or backwards of the old holes and hoping your core is still in good shape, or start looking for a new ski
(core doesn't look too fresh to me either, i've had 2 bindings rip out on me and it was always bright springy woodchips, yours look grey.... )
