Not to sound like a smartass, but have you tried the dealer for the boots? I got some a year or two ago for about $30 eachfor the accordian-looking ones. The later little dust cap is like $15, also available from the dealer. For some reason, 35mm sticks in my head, regarding fork diameter. If you can't find any you like, I have a used set of accordian boots in excellent shape from a 550.
The mini guages, I can't help with, although check with the guys at Hondachopper.com, but say it's for a 750 or they won't give you the time of day.

P.S. Powersportspro.com also has the boots, if they don't list your bike, look under a different year or similar model.
