Where to get 1965 barracuda HH1 Copper Polly Paint

Does anyone know where to find old "One Day Paint and Body" (California) shot single stage "Sunburst Silver" or what paint line that chain uses in 1995-ish? It's gotta be close to NN Barracuda silver poly as that is what I asked for and they found this stock color. I need a touch up jar....I know it can be matched but if it were a stock color I could shop around for it.
