Looking to replace my leaf springs and trash the old originals off my '66 Barracuda Formula S. Already spoke with 'Springs N' Things' just need to deicde if I want stock, 1" or 2" over height. Motor is only putting out 285 - 300hp but I'm a big guy - 300lbs so I'm leaning towards the 2" over. I like a little bit of height I used to have when I had air shocks on her a while back. What do you guys think?
