How To Replace your Lower Column Bearing: Better and Cheaper!!!
I added the bearing to my 68 column. I don't know if there are differences is the 67 column. I had to slightly modify my shift tube to make the bearing work but it was easy. My car is a floor shift so the inner shift tube doesn't do anything in my application. It's been a few years since I did it but IIRC I gutted the lower plastic piece and flipped it upside down and sanded the sides so it would slide into the outer column jacket. The shift tube needed to be supported at the bottom. I left the large spring in place so it would push up on the shift tube and hold it in place. I ground off a little of the shift tube to shorten it up a little. I'm not sure if I'm making any sense but it was pretty easy to do. Once you get in there you'll figure it out.
