If you find a good tech who gives a shit he can get you all the parts you need and bend your brakes to fit almost anything. I have. The biggest problem is the spot you put your pole to get out of the binding gets a hole in it and breaks the indicator. Rossi will not sell just that part because it not "user servicable". Most all years of FKS/Pivot bindings have interchangable parts.
The toes should be taken apart and cleaned and re-greased with lithium grease and the same with the heels. The 155 and 185 have the single pivot toe and are easy to do this to. Good luck.
