my bad, my mind saw Certified, not Certifit. Well...with any aftermarket parts, you're going to have some problems. It usually takes a little work to get them to fit. Sometimes you have to take a file and make the holes bigger to get the gaps to look nice. You might have to bend them a little so they won't bulge as much. If at all possible, go with OEM parts, not aftermarket. But if you have to go with Aftermarket...Keystone makes good parts...that's what we use at my Dad's Body Shop.
