Bumper Deletes, Roll Pans 67-69 Barracuda

This may be a exercise in futility, and another thread to get little to no interest response. On the off shot i'm not the only person who has done this or planning to, I'm looking for pictures of front or rear roll pans. I'm fairly certain I know what I want to do to the front, the rear on the other hand i'm torn on. Its a choice between doing a cross brace between the valence and filling in the holes smooth or building a fiberglass roll pan to taper under the rear deck lid for a smoother transition. What ways have been done, and what do they look like?
