This weekend I found another brushed, black button/white "SS" horn cap The same as the one pictured above. The guy selling said it was from a 68 Camaro (he had other parts from the parted car as well, nothing else I wanted, cost me $5) This has a part # of 3928345 BM.
can you please run that number whenever you get a chance.
I read a post from you from November 2009 with a similar cap however the picture was no longer there.
do you still have the cap? is it the same as pictured above?
I now have two, JoeC has one, Ed has a picture of another in the report.
There seems to be something with these caps, If somebody is creating these as suggested,they sure are doing a perfect original job. I have had my car since June 1980, found another yesterday. made the same as all other caps I have seen. I am not so sure the research is over. I sure would like to hear from other 68 SS owners as to what color, plant, build date, and engine.
