Automatic to Manual Column COLLARS????

Aloha FABO!
Ok I know this question has been asked before....I just can't find the thread...dang!

I currently have a floor shifter for my 71 Duster but it still has the automatic column shifter installed. (I did remove the lever)

IS it possible to just swap the steering column collars from an automatic to a manual?

CAN I, WILL THEY?

1.) will they fit? Which different years are compatible?
2.) Can the parts from the auto be reused in the manual? Such as, ignition switch, turn signal cam etc.
3.) Anything I need to be aware of ?

I'm thinking it would be easier to swap it this way then the complete column.

Opinions? suggestion? Ideas?

Plus...shipping would be MUCH cheaper to Hawaii if I got a few light weight column pieces.

I know some of you have ground down your column and made it nice...but I'd rather not go that way.

Mahalo and Aloha!
