Torsion Bar Removal -- Rear Plug

I have a question about torsion bar removal that I haven't seen addressed elsewhere.

I have a 1966 Plymouth Valiant. I'm rebuilding it's front suspension and I need to get the torsion bar out. I'm not planning on replacing them. According to the Shop Manual, you need to remove a lock ring AND a plug before backing out the torsion bar. The lock ring was no problem, but I don't know how to remove the plug. Does it pop out with the torsion bar or is there some other technique. I've attached a screenshot of the page from the manual. The diagram is of a Fury, but the manual doesn't show the other models and it doesn't differentiate in the instructions.

Thanks in advance.
