I never had a problem with clearance on mine. Restored it, put the same parts back in, and suddenly had 1/4" interference between the header and the torsion bar. I tried every single possible way to clearance the header prior to installing the torsion bar, I couldn't make up the 1/4". Finally, put a very heavy, 4' long bar in the end of the header and went nuts on it. Surprisingly, I was able to angle the header just enough to give me the 1/4" plus about 1/8" more with no ill effects.
