Column shift converting to B&M floor shifter

Hello everyone! I'm thinking of going with a B&M Quick Silver shifter.
Currently, I have a '75 Scamp 383/727/8.75 - column shift.
Other than the shifter, which seems fairly easy to install, what else would I need? I know they sell a steering collar conversion piece, but could I keep mine in Park and remove shifter on column? What did you do about the steering lock? Any thoughts or experience on this?
I appreciate the input! Thanks!
