This set of knobs is for 1968 Cougar / Mustangs without factory console. The exception to the rule would be the XR7G. Cougars equipped with a console need the longer version of this knob to clear the padded console face. If you happen to have a 1969 or newer radio then the radio has longer shafts and these knobs may in fact work with a console. 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, if you need the white spacer we offer it here. Keep in mind the
reproduction knobs for the console equipped cars
will work and do not look out of place.
