Are these A body dashes interchangeable? I.E. could you bolt this into, say, a '67 Barracuda and retain all of the functionality? Forgive my ignorance, I'm pretty new to Mopars. Thanks!
Yes if done completely which means speedometer head and cable would need be matched set of 67 or 68 up and the heayer controller would need to be 68 and up, and the radio would need to be 68 and up.
The main harness connections are all the same, except for the hazard flasher. The switch and connector moved in 1970 I think.
So that's all the differences I can think of. from 67 through 72 that aren't cosmetic. The pics should how wrong it looks for a 67.
