Help

I just bought a 62cm Fuji Special Road Racer frame to convert to fixed gear. I just realized I might be in a little bit over my head. I still need:

22.2mm quill stem

26.4mm seat post

Saddle

70mm English threaded bottom bracket

Crank set

Fixed gear chain ring

Chain

Either 126mm Fixed hub, or 120mm hub with spacers

Some bullhorn handlebars

Front brake

I have just the frame and fork. This is going to be my summer project. I guess I need to get a decent job, because this might get expensive. Erik, you told me before you'd help me with a fixed gear, so I'm going to hold you to it. If anyone has any old parts they'd like to donate or sell for cheap, let me know. I think my biggest problem is making sure everything is compatible. From what I can tell old Japanese bikes have a 70mm wide bottom bracket, which is standard for Italian threading, but use English threading, for which 68 cm width is normal. This is so confusing, if anyone knows what they're talking about, please help me.
