Mine was sitting high too, (supposed to from factory), but I thought I wanted to lower it....mine is 69 and former owner had worked on the front end so I dont know if those front springs were correct(or what was in there)...But I did cut one full coil off my front and car sits nicely now, and rides somewhat stiffer.....I run 245x60x14 tires , and seem to do fine...only put 100+- miles on it since that was done, so not sure if any problem could pop up later, like w passengers...
Not knowing your year model or tire size, cant tell you it will work, but I can measure mine , well opening to ground all four wheels if that helps (if you have 69)...
you could possibly lower it less w coil spring adjusters that clamp down the coil too?
