72 Dart Torsion bar replacements??

Well, I was driving my Dart last year and started to notice the passenger side was sitting low. Then I noticed the whole front was kind of low now. I crawled under the car and the drivers side is .25" from the bump stop and the passenger side it just sitting on it. Passenger side has the adjuster all the way in just about. I might have a bit more threads from the drivers side. It's a 318 original car, and these are the same torsion bars it's always had.
Is it time for new torsion bars? Or what's going on?
P.S. I checked for structural damage on the car, all is well.

I've been looking for new ones online, is there a place that sells US made bars? Also, I can only seem to find 1.03 bars...
Any help is appreciated!!!
Thanks guys!
