....or do you already have the headers and just need the T-Bird? LOL. This T-Bird's engine bay is completely packed.
Fortunately there has been a company that custom makes headers for that model car.
Here's a link that Tjerk once send me. He has installed those headers and as far as I remember he's very satisfied. Just call him for more details if you whish.
