I recently put a set of Cal Traks on a customers 79' Trans Am street car. What a difference! The car wouldn't hook up at all before. It will plant the tires and scoot now, all on street tires. I was impressed!

Caltracs will work well for you.

Caltrac springs, Caltarc bars and some good double adjustable shocks would make a huge difference.

You won't need rear sliders, shackles will work fine. When set up with Caltrac's, the rear will be just as stiff as it is now. They do not allow the rear to squat one bit.
