+1 to the rundown from Mr. Wall
you've got a hodge-podge of parts there, but that's not necessarily a bad thing. the aftermarket adjustable(?) upper control arms are a nice touch and evidently somebody put some money and effort in on that.
besides the annoyance factor of having to piece together the rebuild bits all the stuff there is functionally decent items.
don't beat on the idler arm. if it's in good condition reuse it. thems be expensive and difficult to source good quality these days!
