The Project Pad

Hello.. I'm swapping suspension in my 4000 to the two piece uprights all the way around. I'm looking for rear ball joints and having trouble finding the correct ones. Does anyone know the part number for what I need? 2 piece rear upright and stamped control arms..
Please and thank you!!!!
