Check and SEE if you put the clock knob in the ashtray?..:)
Anyhow, LOOK closely at the shaft upon which the knob slips onto ..I believe it's indexed so the knob won't turn and the inside of the knob is also indexed ..The screw just holds the knob on..It's not the tightness of the attaching screw that keeps the knob from turning when you pull out to set the clock's time.
Try installing the tiny screw into the stem of the clock WITHOUT the knob until it bottoms out..Not too tight, just lightly snug.
Measure the length of the screw thread protruding ..Measure the distance from insert for screw head on knob to back-bottom of knob..
Assuming the replacement knob is correct, it should fit on..Good light, correct size screwdriver, steady hand..
AND check the ashtray on the console for the old knob..:)Jim
