No holes were enlarged to accomidate any new size screws. Bruce matched up his two outside holes and used same size screws. I matched up 1 each of the far outside holes but afte we got it up I simply shot a screw threw the bottom of the bumper in the meat of the mustache. There is no reqiurement to really match the holes if you don't want too. You can not see any of the fasteners once installed.
You can see mines are small screws attaching the spoiler and undertray.
