Early 'A' Body Steering Columns

Are all early 'A' body steering columns the same?

I suspect that they all are the same and I plan on moving to a floor shift (B&M Unimatic). Thus, I want to delete the tranny shift lever and the indicator on the top on the column, and need to know what to look for.

Thanks in advance.

This is in our How To Section. Just a thought.
