I think all 3 pins are the same. But it's been a long time since I used them. So far I haven't found the springs for the heel but I doubt you need them. My parents may have my xc skis from when I was...

Would these work for you?
Not sure if they're worth shipping, but I'm not using them and they're taking up space in my box of binding crap. 400398

Looks like these may not be ideal for this thread but they are getting no use at our house. Located in SLC.

Some Old Junior Kastle skis, Bindings are useless and I can remove them.
$5 + shipping...
