So I'm just about done with a ss build for the gf (hopefully she rides the damn thing more than a couple times). Anyways, I'm having trouble finding a set of silver or black front/rear brake calipers that will work on this thing.

It's an old Shogun road frame, which I think originally had 27's or something, but I'm running 700c wheels on it. I mocked it up and measured, so looks like I need a caliper that reaches at least 72-73mm. I'm not even sure what the technical terms are for the different styles, but it doesn't have recessed mounting holes and needs the regular old school style nut/bolt, not the new kinds with a shorter allen/hex head.

This is the last piece so I can get the bike ridable in time for her bday next week. Can you guys help with links or suggestions on where to find what I need? Or, as an alternative can I just use a newer caliper and just source longer nuts/bolts? Thanks so much!
