Re: Bumper ports?
They're supposed to be for towing eyes. You remove the plate and screw in the towing eye. If you do a search on this forum you'll find quite a bit of dialog on this. Like, no one can find the towing eye in the car and some people ordered them from Cadillac and some people took the plate off and there was no place to screw the towing eye into and then the plate would not go back on.
