Recently I picked up some upper and lower rear control arms by Currie Enterprises and a Hotchkis pan hard bar. All of which are adjustable. They've been sitting on my floor for about a week now and I don't have much planned today so I was wondering if anybody had some advice as to the order I should install them in? Or if it really even matters.

My thought was upper control arm first because it seems to be the most difficult then lowers followed by panhard bar. Or maybe panhard, upper, then lower. I'm not entirely sure so any tips would be greatly appreciated!
