I did the same except I cutt a smaller hole around the inside of the rubber ring and painted the nutt black. oh and to make it look good if ya like chrome that is cheep go to the local hardware store and get a chrome sink cap and some 2 sided 3m tape cut all the little tabs off the back and use the 3m tape to stick it on the front of the nutt. I cant find my camera to take a pic but trust me its a great cheap mod. $1 for the chrome cap and like 3 for the tape.
