I have a 1985 Sierra Classic 4wd. I ordered the RC 4" spring lift front and rear. However after I installed it, the truck seems to be a lot taller than I think it should be. I'm thinking I got the 6" instead of the 4". I have 35" tires and was wondering if anyone has a measurement from ground to top of wheel opening/ fender trim edge at the center of opening. Any help with figuring this out will be greatly appreciated.
