Hi,
Not sure your options, but my car has no AC but my doner frame was a AC car which raises the front a bit, for the rear I used a set of rear springs from John R spring, that were made for something else, they were a variable rate, so had to cut part of a coil bend off to fit the pockets which gave the car a nice rake IMO, and doesn't sag even with 3 adults packed in the back.
If you want pm me a email adress and I can send you some pictures and maybe dig up a part number for you, doing on my phone so not the easiest to resize pictures and post.
Or look under projects last summers project or something like that.
Regards,
