Figured I'd post this since our cars are getting up there in age and the TPMS batteries are close to their end of life.

After digging i found out the standard SS uses a different TMPS, one with a rubber valve stem. 1LE, ZL1 and Z/28s have the metal valve stems which these are. Also if needed heres a link to the sensor nut that holds the TMPS in place
