Valve guide for YEP-202M?

[Euphonist]

I'm in search of a valve guide that fits the Yamaha 202M (normal Yamaha ones are too large). They are a bit smaller, almost the size of a trumpet guide. If anyone could help by telling me where I can find one (or a set), it'd be much appreciated.

Try Mouthpieceexpress.com.
They stock lots of parts.

Bring your horn to a local music store. They should have something that will fit, if not something close to the original can be modified to fit.

Thanks, I'll try both.
