[oletrucks] Quick steering column question

["BORDER,RYAN (HP-FtCollins,ex1)" <ryan_border@hp.com>]

Getting ready to lift my cab, and have one question about the stock steering
column:

How does the stock (3 on-the-column originally, I think) steering column
separate from the old steering box on the frame?  Do I just yank it apart?
If I had to guess, I'd guess it comes apart at the arrow in this pic:

Correct?  Are there any special tricks I should know about? 

Thanks-
Ryan.
