Instability Question

What breaks do you have? If you changed to disc brakes or something you could have changed the track which would have a big change to the bumpsteer geometry.

Yes, as I said in an earlier post. I went from a 71 disc brake setup to a 73-76 BBP disc brake setup. swapped the spindles side to side to mount the brakes in the rear to clear the sway bar and such. Something definately changed the dynamics for sure. Can't change it back now, just need to know how to fix the problem.
The answer may lie in some of these kits I have been reading about, tie rod end kits to level the tie rod.
