64 Valiant 360 Swap HELP.

First, being a PUSH BUTTON trans, will this be difficult to convert to a floor shifted 904? is the car originally a v-8 car or 6cyl? if 6 cyl you'll need a v-8 trans anyway so just buy a non-cable trans.. then it will use any after market floor shifter easily..

Secondly, I would wanna go disc brakes, would it be better to buy a kit, or I believe you can use other later A body stuff.
i like the 73-up stock abody set ups.. most after market kits are just copies of this anyway.. it will ba a large bolt pattern so you'll need to change the rear too.. no big deal and a lot more wheel options out there for large bolt pattern.

THIRD, can you just give me some tips on things to do/use?
its a real easy swap.. stock manifolds will choke that 360 some.. tti and dougs both make headers for that car. make sure the cooling system is up to snuff. k-frame stays the same and schumacher (engine0swaps.com)sells the proper motor mounts for the engine. like stated you'll need a v-8 (drop centerlink) to clear the oil pan..
