Nice clean set of four used radio knobs for your 69-70 Mustang or Cougar. No peeling or cracks. The inset picture shows the used next to the new from the backside. The reproductions are shown on the right. Whereas the repros are nice, the originals are still superior. The radios that would not utilize the white plastic spacer would be 1967 radios with factory rear speakers, 68-70 AM radios with rear speakers and 68-70 AM-FM radios. White plastic reproduction spacers available here
. The white spacer is needed on all 1967 radios, and all 1968-70 AM only radios.
