WTB some bike parts.

I'm looking for the following parts, used is perfectly fine, would like to see digital pics if possible. Reply or PM me here if you have anything that can help in my search.

Thanks.

Stem: 1 1/8" threadless, 90mm, 17degree, 26mm clamp. Black color
preferred, aluminum or carbon is fine.

Front derailleur: Two options here. Either 34.9mm clamp to convert my
braze-on Ultegra to fit the new bike, or buy a new derailleur with a
34.9 clamp. Prefer Ultegra or Dura Ace 9sp or 10sp double.

Rear derailleur: Not needed, but would be interested in upgrading to a
Dura Ace 9sp or 10sp derailleur.

Seatpost: I need a longer seatpost, and this frame is a funky size
tube. Because of that I need a 31.6mm diameter seatpost, or a 27.2mm
with a shim to fit the 31.6mm tube. I can get a shim later if someone
has a 27.2mm post to sell now. I'm not sure of length yet
unfortunately. I'd also prefer that this be black color, aluminum or carbon
is fine.
