Should fit the 66 Barracuda just fine. Appears to be the same unit as in my car. I have a gold one I might be parting with in a couple weeks or so if I can repair the black one for my car.
might as well go ahead and box it up, even if I don`t buy it, it`s a decent price.(unlike a bunch on here!)
how much is shipping to 74021 collinsville , ok ? thanks, bob
