70 Swinger 340 Radio
It's the same radio as a 68 and 69 barracuda, but the difference Is the radio dial face says "solid state by Plymouth" and the 70 one year only radio face says "Chrysler solid state"
Originals are hard to find and the prices usually reflect the rarity. Even harder to find is the hardware to mount it. They take flush keyhole bolts on the front.
The thumbwheel radio for 70 was one year only and unique to A body and unique to the rally dash.
