question

I met up with aguy local to me who was doing it. Get a long chunk of square steel, measure your shock towers in back, then cut off a few inches of the box on the left and right side so that you now just have a flat piece of metal on either side. measure and drill a hole on each side, then flat side down, bolt em on.
 
I have a book at home that tells you how to make one (and other parts) for the Fox body Mustang. Mustang Tuning Guide 2 I think is the title. It's a2 book thing. Mustang Tuning Guide 1 is about engines and 2 is about suspensions.
