Man, I searched all over for some 4-40 or 3mm vib isolation mounts...not much luck. I came across plenty of 6-32 and larger sizes. I snagged some of 6-32 ones from old equipment at work. I think I'd have to enlarge my FC mount holes for them to work though. I'd really hate to dot that. Your linked source may be the way to go...unless someone finds a better source in the US.
