How should my car sit?

I have a 67 fastback Cuda, I mini tubbed it and moved the spring inboard 3"
I decided to use body springs because S/S made the car sit up too high.
ride height of the car was about 27" in the back and 25" in the front
I had the spings Dearched 2" it now sits 25 1/4" in the backand and 25" in the front

things to consider you ever decide to do this, in other words mistakes I've made.
can't use standard shocks for the car
Frame boxes at the rear of springs have to be slit ( no big deal )
interior sheetmetal relocated
I used Urathane bushings ( they sqeek all the dam time )

all and all I'm very happy with the car but I could have used some help earlier on and saved some money. this Web site is a perfect fourm for these types of questions
