72 Scamp Lower Column Bearing

I am currently in the process of rebuilding the steering column in my Scamp and I am converting the car from column shift to floor. I have looked at every parts catalog I could find online and can not find a lower bearing for a column shift, just floor shift. I also have searched the post here trying to see if anyone has made this switched and I have come up empty handed. My biggest question is, are column shift and floor shift columns the same minus the shift tube in mine and will the reproduction floor shift lower bearing work in mine without the shift tube? Or is there another way to accomplish and over come this issue? Thanks in advance!
