3 Speed Column Shift Adjustment

[kenk]

Greetings! New here and working on a 70 c10 with column shift issues, and found the very helpful adjustment thread by Green Machine, however I am somewhat stuck (thread closed so starting new post).

I was able to follow and get all 3 bolts loose to adjust the cam bolt, however I can only get it to move half way counter clockwise (all the way clockwise), and i'm not seeing much change in lever space. I tried lubing it pretty liberally, and it moves smooth up until about the half way spot, then it just stops. Even tried tapping with a hammer...

It slips out / jams out of gear (when going from 1st to second), so often now i'm tempted to convert to floor shift (but really like the column shift).
