If the bend and dents arent too bad I would encourage you to renew your original. There are guys out there who can pound them out to look new again. There is a thread here somewhere about a gentleman who does this.
The inner egg crate grills are a little harder to fix because they got brittle over the years. I had two and cut and glued them together to make a good one. A good used one can be found with a little patience but a repop would probably work ok too. At 20 feet there are few who could tell a repop from OG.
