I just installed a set of flowtech afterburner headers on an 81 3/4 ton 4x4. What a pain, and the instructions say use original factory bracket for the A/C, this in impossible without cutting the factory bracket as far as I can tell. Has anyone done this on a truck with the short A/C compressor. Pictures would be great. These things were the worst set of headers I have ever installed and I've done a few. Anybody with headers and A/C please help!!!
