Help with brakes and spindles

[tdub19]

I have a 69 longbed which is being bagged. For the front ive taken the crossmember out and chopped it 1.5inches. I went and bought some 3" drop spindles from chassis tech. It says i need disc brakes and an upper ball joint from a 73-80 c10. Do any of you know how to convert my front drums(power) to accept these disc brakes. Do i need a new master cylinder, proportioning valve, lines, ect. Does anyone know a good place to get some discs, calipers, hubs, and whaterver else i need?
