Have you actually ever BROKEN a torsion bar?

I have a pair of A body 1.03 T bars for sale locally. A guy called today asking about them. We got to talking and he asked if they were marked left and right. He decided to pass on them since I told him that I didn't know which was left or right.
I've heard the warnings: Dont swap them side to side, Dont switch them end to end....But in 30 years of messing around with these cars, I have only seen ONE broken T-bar, and it was a skinny slant six spec unit. The bars in my Charger were pulled for a front end rebuild and reinstalled before I heard anyone warning me about maintaining their original orientation. No failures yet.

What are you lookin to get for them?
