Wheel Bearing dust caps

Does anyone have a source for these? I'd like a couple spares, but can't find any online. . . the junk yard ones I've looked at were beat up worse than mine (if possible!).
If not a source, how about the specs? What diameter did Mazda spec these at?

thanks!!

Yep, that's where I ended up also. I now have two in my spare's kit, I should buy two more.. I am mostly worried about hub flex as a cause for losing them; I might be overthinking the situation., not sure the RA1/ Hoosiers generate enough grip to flex the hub. . . Anyone have a chronic problem losing these?

I think the problem may be linked to heat and component growth. Why not put a little dab of high temp sealant on the mating surface of the dust cap?

I've seen them siliconed on. Safety wired on. Even had a little pin hole vent drilled in the center of them. All various attempts to retain them that appeared to work.
 
Quickshoe is right. Heat that builds up pressue in the rotors is just enough to pop those bearing caps off. A bit of loctite (red) around the mating surfaces have worked wonders for me. Haven't replaced one since I started to use that stuff.
