I have not had to time to bolt them up yet, but could not resist just holding them up there by hand. The fit to the tub is great. In fact, I consider it to be better than stock. The stock fenders have what I consider a flaw in that the front inside edges curve down away from the lip on the tub. The plastic probably just does that when it comes out of the mold and cools. I added a web that goes up against the tub which connects that front lip all the way back. This retains the shape of the lip so that the fenders stays matched up to the shape of the tub where the tub overlaps the fender.
