Most popular tach in the 70's and other stuff

My 72 Duster 340 had an in dash Sparkomatic am/fm cassette with under dash 8 track, 40 watt power booster tied to 4 Pioneer 3 way speakers, a 40 channel cb to keep in touch with my crusing buddies, sun super tach II, and both rear side windows were full of stickers to broadcast what was under the hood. I could rattle my mirrors with those pioneers and power booster, and the rest of the car with that ratty General Kinetics cam. Good times
