1 piece or 2 piece steering column/shaft

[cgster]

I know the 67/68 columns were 1 piece and the later years were 2 piece column/shaft. At some point, someone has switched the column in my 67. I only know this because my truck was originally a manual/floor shifter and now its an automatic. I ordered a new automatic/tilt steering column and not sure if I need to order additional parts to make everything fit correctly or if I can re-use parts that are currently there.
Based on the attached pics, is this column/shaft considered 1 or 2 pieces? Thanks.
