I have a few pair of 3D (these are super hard to find), EST & 4x4 Reflex binding discs for newer Burton and Step On bindings. 3D - $15 & EST/4x4 - $10. 3D fit all older Burton boards before they went channel and 4x4 fit most other brand boards. Message with any questions, Pics are helpful if your unsure on compatibility.

I also have other binding hardware for toe straps and high backs. $5-$10 depending on what you need. See my other ads. I frequently travel North from Sandy to South Ogden so a meet up somewhere in between is doable.
