You want a component type speaker with separate leads for the tweeter and woofer, but in a Camaro you need the tweeter to be co-axially mounted (not to be confused with a "coaxial" 2 way speaker). Component sets like this are sometimes called "convertible".
Not too many companies make convertible components... MB Quart, CDT, Cerwin-Vega, Powerbass, maybe Rainbow...
Not trying to steer you around but the CDTs are nice and go right in, with good reviews all over this forum. https://ls1tech.com/forums/stereo-el...selection.html
Be sure to read the FAQ.
Edit: Damn WB beat me to it!
