guy, i need to replace my front bumper impact strip and license bracket on my 1990 chevy k-1500. i see on the ends of the strip its held on with a nut on each end, but throughout the rest of the strip it looks like plastic push in plugs that go through the bumper. do i just take the nuts off each end and the pull on the strip to remove, and just push the new strip on ? want to make sure i know what im getting into before hand. thanks.
