My bad, the part looks nothing like a 16mm washer after I checked. But check the brakes that the bike came with. Many times the stud would get stuck in the brake and look like it's part of the brake too.
It looks like Paul from Rock Lobster is able to help me out on this one. I appreciate everyone's messages about it. It seems that the brake stud thread size is standard throughout most of the Bontrager line. I guess I could have always stolen the studs off of my brothers Privateer. Which by the way I need to take pictures of as it is a bit unique.
A few updated shots. Put the Marzocchi Atom Bomb fork back on, added an Izumi chain, and White Industries Dos Freewheel! Waiting on the Eno rear wheel to be built up at the local shop, then the build will be near complete. I wouldn't mind having a gold ano seat post to throw on there. Going to order some decals from Gil too. I was thinking about a Yellow Flite, the local shop has them NOS.
