That's Rayzorsharp's car, and the taillights aren't actually all that expensive. I believe you just need some stock 67 or 68 Cougar lights and the fiberglass reproduction Shelby tail panel for a Mustang...
Those lights are pretty expensive from what I've seen. '67/'68 Cougar lights are totally different from those.
I thought the Shelby lights were just Cougar lights without the chrome trim. Could be wrong though... Maybe I'm thinking of someone else with Cougar lights.
