Wanted - bits from your parts box

Hi all!

Due to having an unforeseen crash and buckle, I'm looking for some new bits to build up an old road bikes singlespeed:

1. Brake caliper set. ideally 105, ideally black, but any good rim brakes are cracking.
   
2. Bar tape - got any you over ordered in your parts bin? I'll take it off your hands!
   
3. cabling kit - I need new cables. All my spare cables have disappeared.
   
4. 27.2 seatpost. I'm not fussy! please be cheap.
   
   

Any help would be great!! I also need a new BB, but I still haven't checked what size would be good!

Miles
