brake dust cap size?

Apparently, no auto parts store around here can find what size it is. I need the rotor bearing dust cap (both of them for the front) for my '86. Anyone know what size I need or a site that i can buy them from?

they are 2 1/4 inches. i can get you some off my parts truck if you want. let me know

that helps alot. I'm going to try and find them locally. I need them asap... as my bearings are exposed. If I can't find them I'll be sure to send you a PM (though, I don't seem to have luck buying anything from people off this forum).
