LMI has in stock the Mid-size Teardrop Tortis that I think would fit the 000, in contrast to the Small Teardrop for an OM. Same size soundhole radius. Call them to confirm.

LMI also provides PDF profiles of these guards in scale to a ruler, which may help you verify fit.

I've purchased three from them, and was pleased with the fit. Sometimes the pre-cut guards can be a smidgeon off the radius. If you have an experienced tech nearby, you could by a sheet and have him fit it to your guitar.
