I was trying to take off my front bumper cover on my 2008 Mazda5 but the 8 bolts on the front lip underside were so rusted that in trying to unscrew them, the tabs on the bumper cover tabs with the holes in them for the screws broke/twisted off. Is there any way to repair them or do I now need to find a replacement cover from a boneyard that has the intact tabs? I'm concerned that leaving this unsecured will allow wind to rush in at highway speeds and cause other noises and vibrations and rattles. THANKS!
