An easy way to see if it is bumping in or out is to take out your RF spring. Put it back together. Block your frame at ride height. Lean your creaper against your tire with the creaper on it's side. Jack under your lower control arm until you reach 3-4" of comp. Watch the gap between your creaper and the tire. Gap in the front=bump in. Gap in the back=bump out.

Sounds like you have Pinto spindles. Does your car also have older Nova lower control arms?

The spindals are or what i thought they was was the med size metric spindals the lower controls arms are the chevelle 68 to 72 as the same as the front clip i did not have any problems with the front end stuff on my old car it has the same frontend as my new dw i am also running the chevelle drag link pitiman arm idler arm and another thing that is happening is i have 1 1/2 neg camber on the right front and in 3inches of bump it goes to 5 1/2 neg is this right or wrong as you can problably tell i don't know much about frontends it has all the longer balljoints i just don't know what i need to do
