Super Stock or Stock Style Leaf Springs for my 69 Barracuda.

If you think the shake is from the springs, just C-clamp or F-clamp them; 2 on the front , 2 or 3 on the back.You know, carpenters clamps. That should lock the springs up pretty tight. Maybe get a helper to put eyes on it while you take off.
-Of all the Mopars I have had, I have yet to experience wheel-hop.Even cars with 6 cylinder springs and healthy teeners with sticks.Or even my 420hp-360 and worn out and sagged 318 springs. I currently still have those teener springs with a nearly full main leaf added, eye to eye. They're a 2.2 60ft, but sweet street springs.
-I just hate to see you spend money where it might not be needed.Or maybe they don't solve the problem.That would be a downer.
