I just installed the Viggen IC and in order to do that I had to remove the bumper. It all went back together very easily. BUT I now have about a 3/16" larger gap between the top of the bumper skin and the bottom of the corner markers. Also a bit larger gap by where the bumper skin meets part of the bottom of the fender. The bumper all seemed to 'pop' back in place ok, but it's not the same any more;oops: . Is there something I missed??? Is there a trick to get it to align like it was originally?
