Bringing this thread back from the dead.
Heading up to Mammoth tomorrow. Waxed the SL-R and was putting the K2 Formula bindings back on Monday night when I noticed I was missing the same screw and nut assembly for my back foot. Must've lost it on my previous outing. Submitted the contact form to K2 that same night but haven't heard anything from them since. BA did remind me that they might be busy with SIA.
So last night went to Lowe's and bought a 1/4 x 1/2 carriage bolt, lock washer, and stop nut (with nylon to prevent loosening)for $0.30. Reattached the highback to the heelcup and it's snug so it shouldn't prematurely fall apart. Hopefully I hear back from K2 about getting the correct replacement parts.
