Where can I get the plastic center wheel caps?

[svaillan]

Anyone know where I can get a set of 5 factory plastic center wheel caps and not have to go through my Hummer Parts and pay an arm and a leg for them?

Reason is I am taking mine in to be painted to match my powder coated wheels. I would like to go ahead and take in a second set at the same time becasue my wife is still undecided if she is gonna have her wheels on her H3 powder coated or not. Be cheaper to have them all done at once and if she decides not to it gives me some spares. Thanks, Steve
