Mmmm... At the very least, they also had a chrome oil filler cap...
I also found this: Is it a Sprint? ...which might give you a little more information, though I can't vouch for the reliability of the source... This individual also fails to mention the chrome oil filler cap, but most other sources on this subject do include that feature as part of the package.
If you google for ["Sprint 200" mustang], you'll find quite a few sites with pictures.
