We’d guessing 1970 because of the 400 c.i.d. engine. Per wiki, the 1971-73 T/As had a 455. My second cousin Shirley drove one of those 455s. However, we’re skeptical of the “T/A 6.6” on the shaker. It should say “400.” But, they came in white or blue. We’re also a little leery of the screaming chicken. That came on-line for 1973. I guess the verdict is “frankenbird.” It’s still sexy as hell.
