I have 4 tire pressure monitors that came out of a set of C6 ZO-6 wheels. I don't know if they work but I suspect that they do because they came off a running car. I will give them to whoever might need them for their car. You pay shipping. If you are interested send me a shipping address and I will get you a quote from UPS. Then you can send me a check for the shipping amount and I will send them to you right away. I will send them anywhere that UPS will ship to. A PM will work the best I think.
