The best route to go is to have some made for the car from good round steel tubing. I just so happed to have these on my car. I can give you the name and number of my friend who is a certified chasis builder. He will build them from scratch at his shop in Plant City.

Oh and BTW you need to start buying the Muscle Mustangs and Fast Fords magazine as well as 5.0 magazine. There are vast amounts of info. in these mags especially on your car. They seem to do a big '03 Cobra article every month now. This month MM&FF got a '03 Cobra into the 11's with just drag radials and a smaller blower pulley ! :o
