am/fm radios?

If your gonna be looking in wrecking yards I'd cut a template of you holes in a piece of shoe box type cardbard. You could stick it in your pocket and compare it to whatever you find to know for sure. That's if your striving for a correct looking radio. If you want to listen to music, There's aftermarket ones that will fit and probably perform a whole lot better than something very used with 30 yr old technology. When I was a kid and these trucks were a few years old whacking the dash a few times was often neccesary to tune in a station.
