Column ID and missing parts

[68anniversary]

I bought an auto column for my 68. I was told the column came out of another 68 truck. It seems to be missing a few parts at the bottom which doesn't look like the one in my truck now which is a 4speed column. Mine is all one piece to the rag joint. This one seems to have a joint at the end then another shaft to the gear box? I'm guessing the parts I am missing are my lower bearing and whatever holds it in since the shaft slides all the way out. How do I know which year column I have and and the reason I ask is I have seen the lower bearing parts in a kit but the book said for a 69-72 which leaves me out. Anyone here have theirs apart before that can help with what it will take to put it back together?
