Damn Dex, that F**KIN sucks!!! Who in their bright little in-bread mind, would steal valve stem caps? That is just plain f**kin retarded!!!
Dex man, you need to get yourself a rabbit`s foot, four leaf clover, or your own personal little leperchaun! You`re in some dire need of good luck!! Or even better....find yourself a hot irish chick(boobs)! If that does`nt give you good luck, I don`t know what will.
As for the stem caps, they can be found virtually anywhere:Autozone, Advance Auto, Wal-Mart, ect... just shop around.
I hope that your luck changes soon for the best.
