Removing the black rubber parts of the guards on my 73 Challenger is easy enough, but what do you do to fill the notches in the lower valence? Originally, there was a flexible rubber extension hanging down from the bumper guard that covers this notch and one of mine is broken. I'd like to remove the guards completely and have the bumper rechromed, but don't want to leave the notches exposed. Does anyone make reproductions of the rubber extensions? I've checked the board and all the posts I find about this subject are for Cudas. :dontknow:
