Mickmate,
I think you're right, but the T-Bird IRS doesn't have a way to set caster. The lower heim's are captured between conical washers so I can't change spacer thickness. And the upper links are welded.

John,
The T-Bird IRS doesn't have a tie rod. It uses adjustment of the lower pivot points to control toe and camber. The outer knuckle doesn't have any adjustments.

The only thing I can think is to set toe great enough that as it bumps/droops, it always stays in a toe-in position? Would this be correct? I think I am correct in saying you don't wan't it crossing neutral and going to a toe-out setting. To keep that from happening, I will have to run a relatively high toe-in.
