Steering Column Rebuild Question

Simple question: Can a manual steering shaft be installed in a steering column originally intended for power steering?

If you want details/back story, read below..... :happy1:

My car is originally a power steering column shift car. It has been converted to manual steering with the Firm Feel column adapter. Ultimately I want to use the Sanderson headers, which work with manual steering (assuming the slip joint is in the proper place). I have a manual steering column, but it is for a floor shift setup.

Originally I thought I wanted a floor shifter, but since this is not a race car, I decided not to waste my $$ on that part of the project. So now, to use the Sanderson Headers, I need to install the longer manual shaft in my existing power column.
