Pedal difference?

hi fellas i dont mean to rehash this but are the clutch pedal assys the same for all dusters
73 and up? or to put it another way can i use a 74 slant six duster clutch pedal setup in a 73 340 duster application? (if not-what mods are needed to make it work properly?)
also is there a difference between a 73 floor shift colum an a 74?
thanx.
