Default Re: Early Mustang 1" Upper A-Arm drop

When Joe Spinelli was restoring the Super Stock Maverick I had a chance to see the body. It had that mod done to it. This mod is to drop it 1 inch and move it back 5/8". There is a diagram in the old Ford Boss 302 chassis book. Another Ford trick is to heat the steering arm on the spindle bend the arm down right at spindle about a inch the heat the portion that tie rod attaches to and bend that mounting hole back up about a inch the helps bump steer. It's a lot of work but it's worth it.

I have spoken to a few guys and they seem to be split on whether there is a benefit to doing it.. I am trying to keep the wheels straighter on launch, as now the tops of the tires lean in. How did this modification effect your alignment?
Any thoughts?
