[shelby racer]

Shelby sent me a new set of driver's side headers that look like my old ones except that they are rusty and the welds are not as nice. My original box had an "F" designation on the end of the part number. By cutting off the tack welds holding the pipe to the flange I can manipulate it to the # 5 exhaust port over the steering shaft where it wedges between the steering shaft and the body support (NO play for engine or side pipe movement). Unfortunately I also cannot manipulate the pipe in from the top (trying to thread it by the end that will connect with the side pipe) or up between the steering shaft and the body support with the flange on the pipe.
