Steering column length for 67 cab

[Peanut74]

As the title says I am trying to figure out what steering column length I need for my 67. I have the original column but it is one long solid shaft with a collapsible section. Based on what I have found on how to measure I need a 33" which is not a common size. The old one is a three on the tree and I want to go to an automatic on the column and tilt. So for you gents that have converted or replaced you column what length did you use?
Thanks in advance.

I have a different truck(72 GMC), but hopefully this helps.

I bought a Summit Tilt column. I couldn’t figure out the correct length so I got the 31”, as my goal was to get the steering wheel away from me lol.

They sell a bolt on coupler with a u-joint for the end of column to shaft. What I found was, that the end of the column accepts the original upper intermediate shaft. The column is hollow at least to the point that the shaft goes into it a foot or so. So if you got the 33” you’d be good.

I got a u-joint and welded it up in the middle for fun, and pushed the column forward til it hit the dash and called it a day...

Thanks for the info cablescum. The pictures really helped with the explanation. Since you got a 30" to work a 32" or 33" should work for me. But I will hold off for a bit to see what others have say.
