Burton/Rossi Compatibility Question

[North_by_Northwest]

I recently bought a new pair of Rossignol bindings for a year old Burton Floater. Last year I had to scrounge up a pair of special base plates to fit the three-hole Burton pattern so I could use my old bindings. Unfortunately the special plates don't fit my new bindings at all and I have yet to find a shop that carries plates that will work. Does anyone know where to get baseplates made to fit the Burton three-hole pattern boards?

 

Short of drilling my Rossi's (and they aren't the best design to hold up to that) I'm stuck.

 

Fuckin' Burton
