I don't knw but would the instrument cluster fit in mine ?
It should fit, but it's possible you could have some computer issues. The Shelby's had a tune built in that's different than GT's. It may have had some other tweaks associated with Shelby. I assume you mean a Shelby and not a Shelby GT500. You could use the LCA's and some other suspension items maybe.
