65 Barracuda 4-speed???

Will I have any issues swapping the 4-speed and rear end from a 1965 barracuda into my 74 dart? I may be able to get one at a reasonable price, but want to make sure the parts will swap over before I look at the car. I know I would need a new bellhousing to fit my slant, but what about everything else? floor hump, pedals, clutch fork, etc...
