65 and 66 coronet steering wheel the same?

Can anyone tell me what the difference between a 66 and 65 steering column is? I recently learned that the 66 and 67 are significantly different and require the entire dash be changed. I am swapping my 66 to a console car and have found many reasonably priced 65 steering wheels for console cars but very few reasonably priced 66 columns.

I know the horn rings can be inter changed so I guess the wheels are the same. Not sure about the columns.
