I am building up a 2004 Trek 2200 frame and need to know the FD clamp
diameter...this is apparently top secret information, can't find it
anywhere. Anyone know?

Thanks!

Got calipers?

This old thread says it's 35mm:

Mine's 34.9 mm (1 3/8"). Shimano clamps usually have the diameter
forged inside the band. I can see it if I take it off the frame.
