Have had the same problems with my guards. Fit fine right out of the box. Once painted didn't fit all that good. The man that painted them showed me how to sand them to fit. Requires more patience than I have. Result looked good. Right side does not fit as was shown above in a post. Some adjustment in the fascia would probably help this. Did use 2 screws in each side, one underneath and one in the middle of the guard.
