I know this has probably been asked a million times cause its kinda popular, but what is included in changing the rear drums to disc? I am going to buy a conversion soon, so I want to make sure its all there....

 

i would get the knuckle with upper control arm attached, the calipere with the brake pipe and rubber hose attached, the ebrake cables, and caliper at teh minimum.
the upper controol arm attached means easier to install instead of separating your ball joint.
