I still have the street tach. It is in excellent condition. It is just the tach unit with the four power wires: power, ground, signal input, and light signal wire (stock light is light green) and small tach mount plate for mounting on the dash, a pillar, etc... (it has a wire shroud for protection).
I'd be more interested In the Autometer. I did some looking but couldn't find a picture up that went with that tach, maybe you know anything about that?
