Special green paint for 72 Duster

I remember talking to Bruce (7071DartGTReg) (RIP) about cars like this. He mentioned the Shamrock car and also the Sidewinder Satellite. He had pictures of a Sidewinder. It was brown with a brown snakeskin vinyl top, special rattlesnake lookin stripes and interior. It was cool lookin and according to Bruce was available only in the southwest. He said dealers made packages like this all the time, as well as rare location specific factory packages......so who really knows what was available?
