Converting to a manual trans steering column w/a floor shifted automatic

[1974ChevyC10]

i want to add a b&m floor shift in my truck and swap out the auto steering column for a manual one.i dont care if its tilt or not as a tach will be mounted on the column.my questions go as follows
to switch over from auto to manual will i have to use a manual trans truck neutral safety switch or can i use the one from the auto?
in terms of the column swap and the auto linkage which bolts to the column do i have to use manual trans linkage parts with an automatic or the ones from the auto trans?
how exactly does the shift linkage hook up on a B&M truck shifter.

thanks in advance for the replies
