[1960HDGMC]

Hey Steve, This is the better (if you can call it that) of the two speakers I have. This one produces sound, but is very tired. If I can not find a decent original in better shape, I plan to patch up the cone and make do. I have a different looking bracket than I see in most threads concerning factory radio brackets. I would also like to know what the speaker codes are about. On my old guitar amps, I can tell you a lot about the speaker(maker,year,production order,etc), but I need help with decoding this speaker from the truck. It shows466938. If GMC truck speakers follow the same logic as guitar amp speakers from the same era, then 466 is a makers code, the 9 would be the year in the decade produced (in this case,1959),the 38 would be the 38th week of the year produced, second week of October,1959. The other number,7275457,is the Delco part number for 1960 GMC and Chevrolet Truck radio , according to the Sams Schematic information. I will go online and look for maker codes for companies that made speakers back then. Let you know what I find. Thanks for the help, Greg Mead
