I read through a lot of earlier posts regarding shocks and didn't find exactly what I was looking for. I have a 70 Challenger TA. It has air shocks in the rear, but I have since deflated them and had the leaf springs re-arched +2 inches and the stance is now PERFECT. I think I want either Monroe or Edlebrock, possibly Gabriel's (80 each range) but don't want my ride heigth to change. Application is for nice street performance, not serious track work. What are your thoughts, specific part number/names & where to buy?
