I picked a non-ST one off eBay, believe it was from a fusion for $40. I like the all black cover over the regular ST. You can also get the lincoln versions too (although you'd want to cover up the lincoln logo.)
Just some options if you want something different, both usually cost less than the ST/RS ones.
Sorry that I failed to respond. Shortly after posting this request, I found a perfect RS cover locally for $25. I was going to vinyl wrap it, but a friend of mine who does Hydrodipping told me that it would fail quickly, so he ran mine with a batch he was doing for another customer, and clear coated it for me. Mods, please remove this post. Thanks again just the same.
Looks good. Back when I had my ST I had my engine cover hydro dipped with a carbon fiber design as well. It lasted for years but eventually it did start to crack and peel. It is a plastic part that sees a lot of heat so I wasn't that surprised.
