A body - B body spindle swap

Anyone here running B or E body spindles on a 72 or earlier A body? I would like to put the 11.75 disk setup on the front of this 72 once I find some big ball joint upper control arms... Plenty of these B bodies, one 72/73 satellite in particular, in the local yard I could get the spindles / steering arm and lower ball joint off of easily... Sure the calipers and hoses would be junk, but may work as cores or trot line weights! Just figured there would be some pros on here that could weigh in. There are also a couple F body Aspen Volares in this yard, would there be pros / cons one over the other?
