I have a 73 Ford F-350 390 Super Camper Special. I am looking for a set of after-market steel tube headers with collectors to fit the truck. The headers are different for an F-250. The F-350 has the crossmember that holds the radius rods from the twin I-beam axles in a different location and also has a large swaybar that is attached to the radius rods forward of the crossmember. Any help would be appreciated in helping me locate a pair of new headers.
