You can get a new tailgate cap to cover these holes from the dealer. I remember guys asking about this in the past. I don't have a part number but I believe it is a tight fitting tailgate cap that covers the holes.
i called Dallas Dodge parts department.... what a joke. One long frustrating story short, No. UNLESS i buy their mopar cover. They do not sell that piece separately. Hey they only wanted 2,250.00 for theirs, and i quote "it even comes with a wing like the viper truck, that has shown to help your mileage by at least by 4mpg". Ummm... ok, I'll take two!

I did find one at a local Camper and cover retail chain for $39, i'll take some pics tomorrow.
