You do not need to use the filler stip. However, you will have to plug or fill in the retaining holes as a result of removing the filler from your '73. Don't forget you will need to procure a set of the '70-'72 bumperettes or fill in the rear valance gap.




True, you don't HAVE to use the 70-72 filler strip, but as you stand at the rear of the car, by the bumper, and look down, you will see a very noticeable gap without the strip. That why the factory went to the trouble of using the filler strip, and that's the same reason that I did...

I used about 7 self-tapping sheet metal screws to attach my filler to the bottom of the rear end taillight panel. The screw tips protrude slightly into the very lower inside of my trunk, but are not noticeable unless I point them out to someone.
