Broken Silvretta 404s - Fix?

[JDCH]

So, I borrowed my buddy's skis for the winter while he was in flatter places. He has Silvretta 404 bindings. A couple weeks ago while skiing up around chair, I broke the heel riser on one of the bindings (see photos below) I took the ski to Second Ascent and the guy there told me I was SOL, and that he couldn't order me a new part. I am not someone who gives back things that were lent to me broken. I need to fix this ASAP. I really appreciate any suggestions.

And this is what the other one (not broken) looks like:

Marmot Mountain Works in Bellevue has, or used to have, a box of odd pieces and parts. Its a long shot, but you might try them.

You could probably have a metalsmith make you a new piece, but that would probably be more expensive than buying an old pair of 404s on ebay and parting them out.

I know that The Mountain Shop in Portland has a bucket of 404 parts in their basement. If you call them up, they might have what you're looking for.
