Jon, if you have not yet flipped the outer tie rod ends back to where they belong (under the ball joint knuckle), no amount of shock fussing will alleviate your bump steer. I thought I made that clear back when I tried to align it for you. You say that you have taken the Mustang wheels off, so I assume that was so you could put the tie rods back where they belong. Is that not true?

If you are still trying to make the Mustang wheels work on your car, I will simply repeat what Ron, myself and others have told you - get some wheels that fit your car properly. There are other wheels on the planet besides steelies and those Mustang wheels.

I apologize if I have misunderstood your post, and will step aside and let others weigh in if that is the case.
