1966 Dart Hood Torsion Bars?

I believe mine are getting a little weak, you can tell when opening the hood that it feels heavier. The wind has blown the hood close a couple of times also. If I get some used ones I could be in the same situation. Any suggestions on this? Thanks
Are your hinges lubed up good? The trunk rods are adjustable. I don't recall the hood rods are but they may be.
