Early A body Slant/6 to 70's 360 swap

I have a 1965 Dodge Dart GT Convertible, i'm going to pull the slant/6 to a 74' 360 motor and transmission.Said to be out of a Warlock. Would like some advice on what to do with transmission set up. I now have automatic in the floor(cable driven) I'm wondering if there are any kits to change for the shifting on the 70's transmission? I've got a early A Body center link from a 273, the exhaust manifold, and gas pedal. What other things do I need to consider, as far as the engine/transmission go? ( I've ordered the motor mounts from Schumacher) Also have the power steering, alternator brackets. Any suggestions would be great. I'm planning on dong this this fall, and like to get my "ducks" in a row>
