Not sure about the Sportivo lip, but hte Levin definately needs about 6 slits cut into the front bumper so that the top of the lip 'hooks' on. Then you screw on from the bottom. I thought the same and orignally wanted to do it myself. I know I'd have to pay more if I go through a Toyota dealer, but I wanted to go directly to the panel beaters they use, as they'd probably charge more or less the same as any other panel beater, but at least I'd know they've done it before. I'll give JR a try if I can't track down a beater. You've got me thinking now. How come the Sportivos don't have these 'slits' to hook the lip on. If you screw it on from the bottom only, isn't the top part of the lip not very attached?
