OK, so this is a dumb minor thing, but I've got an '08 Impala which came from the factory with a true TPMS, with sensors built into the wheels (apparently integrated with the valve stems.) The caps are teh same thread as a normal Schraeder valve, but they are longer, so you can put a regular Schraeder valve cap on but it'll look silly. Apparently when the tires were replaced the garage lost the original caps and put standard ones on. It's a little thing but it bothers me.
Now here's the funny thing... an online search turns up nothing. Does anyone sell these for cheap, or do I have to go to the Chevy dealer and presumably pay big $$$ to restore my valve stems to their original appearance?
