My 67 nova seems to take bumps and dips in the rode very hard in the rear.I just installed new KYB shocks and it didnt change. So..my question is, Can the rear leafs need re-arching to eliminate this? Or maybe replacement..The cat is a stocker..
theres your problem its not suppose to have multi leaf it suppose to have mono leaf. meaning single leaf on each side.Has multi leaf rear springs..and level stance.
