Want to buy a set of 4 center caps for the 7 spoke GM forged wheels on the C6 Hertz/ZHZ version (same center caps as the 15-spoke forged chrome wheels also). GM parts number 19132700, number on the backside of caps is 88966047. These caps have an outer diameter of 2 5/8" (same as OEM base wheels) with inner diameter of 2 3/8" (different from OEM base wheels). Sample pictures as shown. I'm located in Lafayette, IN, please PM me if you have them. Thanks
Having done a lot of research (and spent a lot of money), the saga of C6 center caps is a long and complicated one. There are at least seven different ones (flat silver on a flat cap, sparkle silver on a concave cape, flat silver on concave, grey (the standard for most polished and chrome wheels), plus a couple of special editions. All are the same size and fit any wheel with the simple cap (not the original base and Z06 wheels that used "hub cap" type closeouts. (They also fit C5 and C7 wheels since I am running a set of C6 caps on my C7 wheels now.) The truly disturbing thing is that GM has changed the caps with the same part number over the years (I orded nine specific part numbered caps, all arrived in sealed packages, but there were three different styles depending on the year of manufacture).
Anyway, here are some photos of a set I have available if they are of interest. All four are brand new.

Do you know what the inner diameters (measure from clip to clip) are for these caps? The wheels I have uses 2 3/8" inner diameter (OEM base wheels use 2 1/4") with the clips being roughly 1/4" tall (OEM base wheel clips are also a lot taller at 1/2" from memory) from my rough measurement.

All C6 (indeed, all GM) wheels have the same center cap dimensions, In fact, the black portion that fits into the wheel is the same part number on all GM wheels (except those using oddly shaped center hubs).
Here is the back of the ones I have ... its the same on all two dozen different caps I have, plus a friend Cavalier. I had a set of the 7-spoke wheels and changed center caps several times.
Those appear to be normal GCA seven-spokes so no reason the caps should fit. However, since you seem to have convinced yourself that you need special caps for whatever reason, I suggest you keep looking. Good luck.
I have a ZHZ and need one of these. One de-laminated and the chrome part is gone. It is the thinner type as Eric shows in the original thread. I purchased a thick one and it does not clip in.
