Has anyone used this disc brake kit??

that's a great find abodyjoe but it's 1300 bucks for the kit, ouch that a lot more then my budget can afford. Thanks though. So what you guys are saying is that becasue mine is a 74 it should already have the big ball joint and therefore i won't need either the ball joints or upper control arms? I just want to make sure i'm understanding you guys right. Thanks all for your help!!
