65 Valiant fender tag question about radio options?

Oh well maybe that's why I haven't found mine. That's the only place the carpet has been disturbed. Instead of fixing it I guess they just let the heater core leak all over the carpet, Wonder why when you see how easy it is to remove. Only chance I have is the build card, which Chrysler has told me they still have on file. But I'm definitely not going to register this thing until I have it in driveable condition. That means pretty much a full interior resto. Unless for some reason it's under the carpet under the seat the build sheet is gone for good. Sucks too, because out of the two Mopars I've got I don't have any documentation on either. My 73 Charger I found remnants of the broadcast sheet but it was long gone.
