Whatever you use, make sure thay are ALL METAL! The natural rubber ones 
weather-crack in a couple of years and have failed on the highway in Panteras. 
There are two sizes of stem assemblies: 1/2" and 5/8" and both use rubber 
bushings between metal stem and the metal wheels, so check to see what size 
your wheels are drilled for. 
I think a few early cars had aluminum valve stems. They save maybe 15 grams 
of wt over brass or chromed-brass. Brass are available at any tire store 
and maybe Kragens. Haven't seen aluminum ones for some time except on 
superbikes. Good luck- J DeRyke
