The right hand knob for tuning just spins on the knob shaft, it doesn't have the "split tube" surround like shown on the left volume knob. What is the part called and where can it be purchased?
I've had this original 66 AM/FM radio for a while and decided to put it in while I was redoing the heater box (and had the glove box removed). I did not realize the tuning knob was freely spinning until I went to put the knobs back on.
