hello=) i'm new here, found this topic when searching lock belts. you mentioned those "d lock belt clippy things". i'm bikemessenger and i LOVE those. when i wanted one myself, i didn't find a place to get them, so i simply made one myself. they don't rattle and you surprisingly don't feel the lock. i recommend removing those plastic or alloy bracket parts of your locks and filling that gap with a piece of tube and tape. see what i mean.
i don't know which countries you all are coming from, but one of these sources should probably send them anwhere on earth: befixed, fabric horse, pirate. i think those three shops would send them anywhere. =)
