valve stems for tpms sensor
 

I broke 2 of my valve stems taking the metal caps off because they were corroded on there. I did not realize this was a 238$ (each) fix at the dealer so I just told them to put normal valve stems in there no sensor.

I kept the sensors and have been looking for somewhere to get just the metal valve stem that attaches to the sensor, this would be an easy fix if i could just find the stem.

Does anyone know who would sell something like that ?? or where I could get a replacement stem/sensor for a reasonable price?

the tpms light on the dash is not a big deal but it does kind of annoy me it's a 2008 mazda 3

Thanks for any insight!
