Header Install ???
I put hookers on my dart (slant 6 to 360 conversion)while it was up on jack stands putting the motor in. I had to take the steering linkages off and run them through the header tubes. I also had to raise the engine up with a engine lift to get them in. Mine also had to be dented on some of the tubes to clear. Welcome to the wonderful world of headers, they sound good but if yours turn out like mine they are a pain to install.
