67-69 column differences?

Hey all, I purchased a 67 barracuda that has some missing parts. I need a column. I am going to look at a column owned by a gentleman who isn't sure of the year.
I know what the early a columns look like and what the 70 and up look like.
Is there any difference I need to know between 67-69? I have heard 67 is a unique year.
And it is a manual steering, floor shift if that makes any difference.
Thanks for listening guys.
