'66 Formula S Torsion Bars

We have 1" replacement bars for our 71 valiant, but haven't gotten it all back together yet. I've read many threads where the people are happy with the improvement with the 1.000" or 1.040" bars and they are not too stiff.

Remember torsion bars act like springs. All springs fatigue with age and use. They will eventually fatigue to the point that they will break/crack. I do not recommend using "old/used" bars (especially when these are getting to be 50 years old). Replace them with fresh ones.
