Wow thats an old thread!! 10 years until someone knocked the dust off of it. I woild suggest replacing the bracket thats ovaled out. Once i repaired an ovaled out radius arm bracket on a Nissan by welding on a huge washer with right size hole for the radius arm. Replacement is best though.

 

Lower control arm driver side



You can see the play well hear



How can i repair this if its part of the frame



This set up would not utilize radius arms?
