Kids bindings.
Marker 4.5 with demo track.
Free + shipping
Note: bindings and tracks came off different setups but I'm fairly certain they will work together. No template but I've got pics of plates mounted so if you're willing to do some 2x4 tests you can probably figure out mount location and adjust for smaller boot as necessary.
