How to pick a torque converter and flywheel?

I'm pricing out doing a magnum conversion on my 72 dart right now and I'm stuck on the torque converter and flywheel. I want to put in a 98 Magnum 360 which I know will bolt up to my a904 but I can't figure out what torque converter to get? It's only going to be street driven. Also will my current flywheel work with only have to notch one hole or do I need to get one specific to a 360?
