Actually the monoleafs were used on all Camaros in 67, and in 68 for the non high performance cars but the main problem with the wheel hop was that the shocks in 67 were both mounted in the back and the torque tended to make the pinion climb the ring gear resulting in the axle twisting downward which would compress the shocks and twist the weak monos into a sort of S shape which would snap back violently and give that evil shudder which is wheelhop. This obviously wasn't good so they put the bar on the axle to the body on the right side which sort of helped but....didn't work all that well. There is no real benefit to the mono leafs over the multis. And the multis have benefits over the monos so find some multis and be done with it. And oh wait...what was I thinking again...ahhh not geezer...still have memory....hmm and Streeeeeetts, when did you go Spanish...?
