Hemi in to 69 Swinger, like to go manual

So, my dart shell has been sitting in storage for some time and I'm planning on getting to it. Was just a 69 /6 auto. A local guy has abandoned his Duster project and has the Gerst rear and front set up for a Gen3. I'm tempted to do the swap, so I've been combing through here to try to research it. I'd like to do a manual. As I understand, the truck motors would drop in without having to swap the oil pan and pick up, but I would have to swap them on a car motor. Only a few years of 2500 pick ups had the nv4500 5 speed or the nv5600 6 speed and the G56 6 speed. Are they suitable transmissions, or should I be looking at a different transmission, or combo from a car, and doing the pan/sump swap? I guess the second think would be pedals. I'd have to add the clutch set up, and there were so many options there. Go Hydraulic?
