Phil,
Others can chime in, but as far as I know, no replacement spring will result in the correct height without cutting them. It will sit too high. With Jerry's help, I removed my springs last year and we cut a full loop out. After re-sinstalling, we determined the car still sits about 1/2 - 3/4 too high. In early May, we will be removing them again and cutting another half loop out. At the time, I also plan to remove the black paint and paint them with natural metal paint, which is the correct finish.
Best of luck,
John
