if you're patient you could get a reasonable price AM radio;
As mentioned the interchange is 1970-1977.

The AM radios all had a script "Delco, but I believe that the earlier ones had the "Delco" in between the 14 & 16 on the radio dial - roughly in line with the tops of the numbers, while later ones had the "Delco" moved to below the 16.

For the AM/FM radios, the early ones are easiest to identify be the script "Delco", while the later ones had a small "Delco" logo in a box.
I believe that the OE dial faces had the "Delco" above the dial face opening, while the later (?service replacement) had the Delco moved on the bottom of dial face opening.
