Where to buy NNN-BC binding bumpers?

Where can a guy buy replacement bumpers (those rubber cubes that fit into the top of the binding for the front of the boot to bump into) for Rottefella NNN-BC Magnum bindings? I went to REI and Fairhaven in Bellingham and they did not have any. I Googled/Froogled and no luck there either. Any leads would be much appreciated!

Try Marmot Mountain Works in Bellevue.

Chances are they will have them in stock, but if not they can certainly order them for you.

No luck on the bumpers from Marmot Mountain Works.  REI sells a lot of NNN-BC stuff but refused to order any bumper/flexors for me.  >

FYI; Fairhaven Bike & Mountain Sport near Bellingham had some on hand but they were for skinnier skis.  They ordered some Rottefella NNN-BC Magnum bumpers from some place back East and also ordered extras.  Medium in stiffness.
