Well the obvious is the face that the 67-72 columns are 2" with a shifter and the mid 70's vans are the same. Just about everything else is 2.25" Including the caddy column that you have spoke about. The column in the 72's are also 35" long. This obviously doesn't apply since you are looking at a tele column. In the end it can be done just be prepared for some modifications to the mounting at the firewall as well as possibly not fitting in the notch under the dash as the factory one.
