Here is the kit that gets mentioned on the forum. I believe it is way overpriced.
Chrysler Crossfire ORACLE Brand Halo Kit
I personally just bought 4 120mm angel eyes and installed them. No one will confirm the size from Oracle, I guess Oracle thinks its a big secret, but I think they supply 90mm for the smaller ring in the lights. See my gallery for install pics. The fogs use 71mm.
