First off, don't ever put air shocks on the darn thing. It will ride like crap and ruin the leaf springs. You really can't take ride height from a fender or Quarter panel lip. You should be going off say for in the front, the lower control arms pinion snubber area (not off the pinion snubber itself say right next to it) of the control arm up to any point, and in the back maybe from the floor up to a spot just before the rear wheel. If you do mess with them your gone-a throw off your front end specs.
Like toe in toe out and caster and camber. By the way its really hard and expensive to get an Mopar into the right spec for handlling. You really want 4-6 degrees positive caster and your lucky if you get 1 degree positive with your average joe. That's for high speed stability for speeds over 70mph, makes a real big difference even if you can get it up to 1 degree positive.
Then you need about a 1/4 to 1/2 degrees negitive camber. Staying closer to a 1/4 will not chew up tires and toe at about a 3/32 out if you can put up with a little wandering. The slight negitive camber and slight toe out with make her handle a lot better and it will allow slight lean in on turns.
With the right tires and sway bars and in your case (a Rag top) the right platform support you can get-em to pull 1 g or more on a skid pad
