Go to your local friendly Honda Cycle shop.
Most Honda dealers keep at least an arms-length dialogue with Tomos, and many carry the 'peds themselves, even if they don't put em on the floor till summer.
If that doesn't work, and you can't seem to find somewhere that carries em, you could try running down cycle shop listings with a yellow pages (let yer fingers do the walkin..) or some of the places mentioned in the 'Resource' links of this site.
If you don't get anywhere then, for whatever reason, just email yer zip code to the addy you see here, and I will find you someone who does myself.
If possible, when visiting the Honda guys, bring the parts and SHOW them to the folks, cause I've gotten many a screwup where the part ordered did not match the part it was replacing (for some reason, this happens a lot with tail lights/brackets), and it's always best that they know exactly what it SHOULD look like in case the picture in the order book doesn't match up.
Best of luck, dude.
