Is there a block lift kit that will fit a 69 Barracuda

Air shocks used to be pretty popular, but they transfer a lot of load to the top shock bolts.

Shackles also used to be popular, but they look pretty ghetto in my opinion.

You can also roll the inner lip of the fender up if you are REAL careful.

Air shocks are an option I was considering. If I do air shocks and use that to lift it I assume that The higher I go the stiffer the rear suspension gets resulting in a bumpier ride?
(Which might not stop me.)
