Manual swap

Hey all, I am the proud owner of a 1974 duster 225 auto, and to make it more fun, I'd like to manual swap it to a 4 speed. I also plan on turning it into a super six but that's besides the point. Anyway, what I'm wondering is about parts. I tracked down someone who has a 1965 valiant 225 parts car with a 4 speed tran, bell housing, pedals, clutch etc that I will need to do the swap. Would all those parts be transferrable to my duster or did stuff change over the years so they wouldn't work. Thanks!
