What is the secret for removing the pull knobs from the cable on the kick panel vents (non-air cars)? I want to install new knobs but can't seem to get the old knobs off. Does the entire cable assembly have to first be removed? I don't think the knobs and the cable are one unit.

you must disconnect the two cables from
vents then remove panel there is two clips
on back side hope this helps

Went through this on my '69. Had to crush the knobs with a hammer to get them off. Tried heat to the point of the knobs distorting, but wouldn't budge. New knobs push on and may need a little glue inside to stay on. Knobs/cables remove easily from kick panels and vents by removing a clip. Emergency brake mechanism must be removed to get the left panel off. von

Where can I get these clips? Any other way to secure cable?

To answer your original question, the knobs are screwed on. I've got a '71 and noticed that on the one missing its knob there are threads like a wood screw. It doesn't sound like they are going to easily come off though. Good Luck.
