This car came with the heavy duty suspension. As I remember I cut one coil from the front springs. On the rear i added new poly bushings then it was to high so I installed longer hanger bolts. It is pretty much trial and error until you get what you like.

I am new here and you may have changed the car since Feb 2014, but I really like the way the tires fill the wheelwells here: post #73

Was that stock suspension height? I am possibly picking up a '74 soon and already rebuilding it in my head!
