For sale is a tested (several years ago) AM/FM that fits the 70-72 GS, GSX, Skylark. Comes with knobs. Price is $250 plus shipping. Part is located in NY.
Nice radio. Not correct for me and I already have 2 for my year. But I like learning about them. This should have originally came out of a 1971 GS or Skylark since it is a 14AFP1, but you are correct that it is correct style for 70-72. You can see the other model numbers for 70 and 72.
