1973 Dart 340 Sport Project
The Schumacher headers were a guaranteed fit, one of the reasons I went with them. Attached pics show the mods I had to make to the tubes to get clearance. On the passenger side, two tubes were hard against the idler arm / steering assy with the engine in final location. I'm using the Schumacher spool mounts, had the engine as high as it would go in the mounts, sitting level, and still had to dimple the tubes. On the driver side, I had to dimple the tubes to clear the torsion bars and the steering box, even though I went with the Borgeson smaller box.
