I've been happy with the ProClip products. They sell a mount for the 98-02 Camaro's found here:

No clue how good this is and to be clear, that is just the mounting base. You would need to purchase something for the phone to attach. I have these in my C7 and Benz with a magnetic base. Both work well.
