67 steering column disassembly question........

Thanks Redfish,
I finally realized that snap ring was the culprit. I got the inner shaft out but now I’m wrestling with removing the shift tube. The old Chrysler Tech videos have one specifically for the 67 column on YouTube and I see the place where you unscrew the Allen nut to release the shift tube from the outer housing. There doesn’t seem to be anything in that threaded hole on my column but it acts like there is and I can’t pull the shift tube out! Grrrrrrr!
