How did you make the bend for the inner fender lip without having the outer part curl in? I used to cut 2X12's into the shape of the wheel opening, cut the shape of the wheel opening in the sheet metal with a space for the lip then sandwich the sheet metal between the two 2X12s, screw it together and then take a hammer and start hammering up the inner lip to make the 90 degree bend. Even with this method the metal clamped in the 2X12's wanted to curl up at the lower part of the wheel opening.
