4sp in a 72 duster

BUT...... will an f-body clutch pedal assembly work in a 72 duster? i dont care about "correct". just what works. And will the 727 crossmember/transmount need to be changed? also, the b-body 4sp i got is a heck of a lot cheaper than a 6-sp. if i were made of money i wouldnt be on this forum trying to find out if the junkyard parts i got will fit in my p.o.s.
