looking for a working am fm radio for 1970 442 or one that will fit.

 

I have a few aftermarket radios from the late 80's early 90's that will fit your stock radio hole. Probably cassettes players, should still work, prices between 25.00 to 45.00 for the better one. I can get you some photos.

 

They have some on East Bay Auctions or EBAY. Get one that works or rebuilt. Or go with the new version for your tunes.
