I am guessing late 70's early 80's. Not correct for the 70 model. I would use it in the 75 because it is so close. 90 % of all radios that were installed were dealer items, so it may be difficult to say what is correct.
I believe it is 1980 Frankfurt, probably ok for '75-'76. AA has the correct faceplate and brick material.
