Front Suspension Bottomed Out

Well was I wrong. Jumped that gun too soon. Thought the K-frame "sleeves" was the problem. NOT! Front end still falling and the K-frame sleeves are just fine. The pins (or whatever you call them) that go thru the sleeves have a tiny bit of play in them, but it seems to get tight when the nut on the front is tightened. Three people worked on this today and no one can find the problem. We all agree that the problem is NOT the torsion bars or upper control arm assembly. The bars were totally removed and all of us inspected them. They are installed correctly and have V8 part #'s. We found nothing missing, broken, rusted, etc., at the rear and front bar mounts. The bars also fit the sockets. We have concluded that the problem has to be with the lower control arms. We just don't know what is wrong with them. Could it be possible that they are the WRONG control arms for this car? Are there different versions for the various bodies?
We do know that something is not supporting the weight of the car after the car moves. The car drops about 6-7 inches. The upper control arm may allow a change in camber but it does not support the weight of the car. Only the lower control arm does this thru the torsion bars and mounts. I certainly could use an old school Mopar mechanic about now. Thanks everyone, David
