Okay... Ive searched and found a handful of results. But my question is fairly basic. Seems like a layup.... But I have a set of wheels. On the rear barrel, there is a hole where one would mount a TPMS... But the 03-04 models of G's didnt have TPMS.... There is a hole on the front for the valve stem then a hole in the back for the TPMS... So does anyone have any ideas on how to plug up the hole, or has anyone ran into this before? Thanks.

So the wheel has dual valve stem holes? Sensors are a one piece unit with the sensor sitting in side the wheel and the valve stem as the external part (aka its antenna). Shouldn't be a place to mount two separate pieces. Posting a pic would help greatly to see exactly what you have.

My 04 has tpms & only one valve stem hole. Also my old Work wheels came with dual valve stems, front of wheel & one on inner barrel. I did not use tpms with the works. Just mount another valve stem to inside barrel.

I can get pics tomorrow. But what now is saying is correct. That's what is happening. What happened with his work wheels.
