steering column information needed

[jmdemon55]

maybe someone can answers a couple of steering column questions i have...
here is the deal, a buddy has a tilt column out of a 79 chevy camper/van. i thought i read somewhere that these columns were a direct fit into the 67-72 trucks. is this correct? are the mounting points the same,are the plugs for the wiring harness the same,etc? the van did have the ignition switch in the dash like the old trucks. i can get it for a steal but i dont want to have to modify stuff to make it work. any info would be appreciated. thanks for your time, JAY
