Need Help identifying these Rims

I reciently bought these rims and there is only three center caps. I figured it wouldent be that hard to find the center caps for them so i started to look around and i cant find the center caps that came with the rims. when i measured the center caps they measured about 2.4". All the center caps i can find are about 2.25" or 2.5" and larger. I am starting to think that these rims and discontinued and will probibly be a royal pain to find the caps for. If you know of a site which sells these rims or center caps or for that mater if you have them yourself. Let me know cuz its driving me nuts. Thanks.
