I have the same 1" MP torsion bars in my 70 Charger . The Hooker headers # 5903 hit the drivers side T bar. I took a chunk of sidewall from a tire and jammed it between them. Its redneck, but it worked.
I later switched to Hooker #5209 headers and it was just as bad. I now have TTI pipes. ZERO problems. They cost a weeks pay, but were worth it.
