Differences in the GT500?

I know this is the 4.6 thread, but this is my comfort zone, plus I want your ideas. I've seen two minor variations of the car's badging. I was wondering if anyone knew the difference or why they are different.


Link number one shows the SHELBY badging centered, and link two shows it all to the left side. Could one of them be a shelby GT instead? I'm confused about this.
