WTB: Shimano Ultegra or 105 triple drivetrain

For a 1 week ride thru Colorado I need to put a triple setup
on my bike. So I'm looking for an Ultegra or 105 level
triple crank, front/rear derailleur (front must be braze-
on), and bottom bracket. Crankset needs to be 175mm;
chainrings can be shot because I've got some I can replace
them with.

Anyone out there upgrade to Dura-ace and have some stuff
sitting around?

Thanks, George
