Air Shocks

I'm considering putting some air shocks on the rear of my 1972 Plymouth Scamp to raise it up just a little. Has anyone tried the "Monroe MA704 Max-Air Air Shock Absorber"? If so, any feedback would be appreciated. Also, if you can recommend any other air shocks that will fit a 72 A Body, I would like to hear your inputs.

The air ride suspension sounds nice; however (and maybe I'm wrong here), it also sounds like it's pretty expensive and has a much more complex setup.

Thanks,
