Yeah I think it's about time I replace them anyway honestly. Definitely do not want to lose one on the road or at the strip. I appreciate the advice. Haha got to love siblings.
They are closing in on being 50 years old, and they are a critical part of your cars suspension. It would also be a good time to look at the other suspension components, bushings, etc. If the front end hasn't been rebuilt recently, replacing the torsion bars would be a good time to do that.
