Valve stem help

[sjh500]

I just had some Lorinser RS-1's refinished and they are ready to put on the car, but then I realized I don't have the valve stems. My ignorant question is...do I need Lorinser specific stems, or can I just get some from one of the tire shops? I saw some for Lorinser's on Ebay for only $20, but in Germany, so shipping would take forever.
Thanks for the help.
