Disc Converstion Help 71 Swinger

I recently aquired a 71 Swinger....buttload of parts came with it along with about everything I need to complete a disc brake conversion up front. My question is what all will i need...

Things I have: Everything from a 73 dart. A-arms, spindles, along with rotors calipers, front brake lines...

I think Im going to need the brake booster and new master cylnder too or isn't that required? Please any information would be greatly appreciated I have never done this before..

PS: also came with the new matching upper and lower ball joints

..I have already switched spindles and a-arms so what I am worried about is If i need the booster or not and what All i need for that part of the job brake pedal and whatnot..and When I mocked it up today when I turned sharply to the right the driversaide caliper hits the sway arm...any ideas? When i looked at conversion kits they dont include anything to fix or change that issue?
