'71 Dart Radio Knobs

Are such things even available these days or do you simply buy another radio to rob parts from?
The tuner shaft is soldered in. So could be replaced with one from another radio. I just happened to have another one from a 71 Dart I parted out so I just swapped them. I never listen to the radio in my old cars anyway, they are just for looks/display. I'd rather listen to the exhaust and cam. Lol
