disassembly of shifter

Hello to all, I've got a console out of a demon and I'm installing it in my 71 scamp. Ive searched the forums for a way to disassemble the shifter itself from the console. I've got it down to the knob but cannot separate the knob from the shifter shaft. There has got to be a way to separate the two i've just not been able to figure it out and i sure don't want to trash it.
Thank you in advance for whatever advice you all have in helping me out with my conundrum.
