Just like our Vettes the assembly from Modernspare.com is the way to go. I recommended it to a buddy of mine at work with a '16 SS 'vert and he needed it shortly after he purchased it. Tire repair kits are fine for small leaks from nails etc but if you have a major blowout at freeway speeds the full size spare is nice to have.
