I am looking at a set of Bushwacker Pocket Style Fender flares that are used, and the guy doesn't remember(so he say's) what year they came off of. I have a 03 silverado, I was just wondering if any one knew what the difference was between 99-02 & 03-07 classic. The part number only has a 1 number difference. It is a 2 1/2 hour drive. I was just checking fitment before I drive all of that way for $250 (half off of new). Thomas
