Steering Column Collar

I'm in the preparation phase of doing a 4 speed conversion to my 69 Barracuda. The question I have is there a way to replace the steering column collar in order to replace/remove the column shift and gear indicator (Park/Neutral/Drive, etc.). I have another steering column that came out of a floor shift car. Is there an easy way to do this or do I have to replace the whole column?

Thanks for your help and Happy New Year!
