Wanting info on a 904 swap from a a833

Its coming to that point in time where the body work on my car is almost done and am starting to focus on the engine and transmission. I have a 72 swinger with a 318 magnum efi running megasquirt and a A833 and 8 3/4 reareand. Transmission needs a clutch but I dont even think I have it in me anymore to row a gearbox. So im looking for someone to point me in the right direction on swapping in a 904. I know im going to need the transmission, flexplate, torque converter, auto valve body, and oil cooler. Is there a write up to do this and where I can refrence the parts that will work with my magnum engine. Ive been looking at parts on summit just wondering what works with this setup.
Thanks
