A good friend of mine just bought a HD pickup,I think he said it's a 2000.I was admiring it for the first time and noticed all 4 valve stem caps were missing.What did these caps look like-were they anything special? I screwed some regular caps on it but if it had something special originally,I'd like to get them for him.Thanks in advance.

 

i work at a ford dealership i'll scope one out and let you know
