1964 Plymouth Barracuda headlight knob won't pull out from dash

A few hard pulls (which rocked the car) and the knob came off. Not the outcome I was hoping for, but it at least allows me to move forward. Thanks everyone for your help. The best thing is no more car yoga. The last time I wormed my way under that steering wheel in front of the seats, my leg cramped up and I thought I would never get out of there.
