Torsion bars and exhaust heat.

My left side torsion bar, in my opinion, is failing. It could just be old. Front left corner has slowly sunk over the years and I have ran out of adjustment on the bolt.

I have no failure of the mounting points. My exhaust does run very close to the left torsion bar, about 3/8" clearance (tti off the manifold system). This causes an isolated heat effected area.

Does anyone believe the heat could be an issue?
