Disassemble OmniStick Prodigy?

[krisbee]

I am just about to get the joysticks mounted when I realized that I must remove the stick to fit through the 1 1/8" hole I made for it in the plexiglass overlay... How do I remove the stick from the assembly?  I peered in there, but nothing popped out at me.

Thanks in advance,
Kris

Update:  I feel like an idiot... I kept expecting the clip to be obvious, but you have to remove the switch plate and the switches to get at the clip.  I see what to do now...
