i know that stock this would fit, but with the springs, its about the width. if that .5 is too much with the springs, you'll rub. most likely under load.
I rolled my fenders using a baseball bat, just jack the car up a little, wrap the baseball bat with a rag and roll the bat between the tire and the fender, be careful, if you use too much pressure you will bend the fender.
