When did ford start putting superchargers in their shelby mustangs?

What year did shelby start using superchargers? I honestly can't remember I'm curious about that.

2007 if I'm not mistaken.

You could get a supercharged GT 350 in 1966 if you wanted it. But very few were made with the Paxton supercharger option though. If you're talking about modern cars. Every 2007-up Shelby GT 500 came with a supercharger.
