Pre-2010 TPMS Valve Stem Caps

[NolimitE39]

I am looking for at least 2 of the pre-2010 TPMS valve stem caps (willing to buy bulk). Firestone apparently tossed out the ones on my wife's e90 the last time she got the front tires replaced and we didn't notice till it was too late to go dig through their bin. The caps were discontinued in 2010 but I'm hoping someone has some on a shelf or is not attached enough to the ones on their car to sell them. Please PM me if you have some. Thanks.
