picked up a complete front suspension

[Fastest32]

I just picked up a complete front suspension off of a 79 including the crossmember. Im gonna strip it down and just keep the control arms and splindles and brakes. I wanna throw out everything Im not gonna use when I eventually do the brake swap. I guess really all Im gonna thow out is the cross member. It has the steering components too. Should I keep all of that too, or is that not neccessary? What about the sway bar? Oh by the way I got it for free.
