Bad Torsion Bar, Bad Install or Wrong Torsion Bar??

Quite the discovery today. I've always noticed the car had a slight lean to the driver's side and felt it sat low. So this week I read up on the torsion bar adjustments and found the proper level measurements etc. then went at it today. First off the car was sitting at almost a 0 difference when it should be at 1 3/8 for a Barracuda. So I figure I'll raise it up and went to adjust the torsion bars. That is when I noticed the driver's side adjustment bolt is adjusted in almost 1 1/8" deeper than the passenger side. But the driver side sits about 1/4" lower that the passenger side. I then notice the "arm" that the end of the adjustment bolt pushes to put tension on the torsion bar is hitting the frame. That's how far the bolt has been adjusted in. I then notice the rubber bumper (proper term?) that is supposed to hit the frame is missing!
I'm guessing its one of three things and my question to the experts:
1. Is it a badly weakened torsion bar?
2. It appears that if I removed the torsion bar, ratchet the adjustment bolt out almost completely and let the tension arm come down that the torsion bar may fit in. What I am saying ....... Is it possible the torsion bar was installed wrong?
3. Or is it possible there is a 6 cyl torsion bar in their by mistake? It is a small block car from stock.
Btw the passenger side is 1/8" from resting on the rubber bumper. I'm embarrassed to say how long I have been driving it this way but I had an alignment done years ago and its the only front end work the car has ever had while I've owned it.
Any help is appreciated. Thanks
P.S. I know an alignment will be needed after all this and I won't be going back to the same place.
