My '73 Roadrunner had one, it was missing. I am replacing it, and running one speaker front, one speaker rear. I found the parts locally. The car sounds so good I could care less about tunes, and I figure with A/C that rear fan moving air around will help make the inside like a freezer! My other cars have tunes, so I thought it would be cool to make it as original as I can. Doubt I could hear the AM stereo over the engine anyway, unless the car is parked............
