removing upper arms / spindles

Rumor has it that the local pull a part has received a
Aspen ( F body?) and a Cordoba either a J or a B,

going to look at it for disk brakes to put on this 68.
believe I will need the upper arms, spindles, calipers and caliper mounts,,may get the master cylinder, brake booster, proportioning valve if they look good.

what should I throw in the tool box? Other than a selection of large sockets, a breaker bar, allens for the caliper bolts,, any thing else?
Do I need to loosen the torsion bars?

thanks
