front ride height concern

Stupid question #1 thru whatever.

A - B = front suspension height

So on a Barracuda, I want the difference on each side between A and B to be 1 and 1/8, within a tolerance of 1/8, within 1/8 side to side?

Do this prior to any alignment steps, yes?

Nothing else should be done, or set, other than what is laid out in the first two paragraphs, before the ride height procedure?

Thank you.

Correct. Before you can do the alignment you have to set the ride height. The alignment numbers change with the ride height, so if you set the alignment and then change the height you’ve got to reset the alignment.
