Torsion bar help 1970 dodge dart.

That is exactly what they did.
The arm swung too low when they slid it in with the t bar, people do that when they can't master lining up the strut rod.
Totally agree. That is the ONLY way you'll get that ride height with the adjusters all the way out. I'd take it back to the shop that did it and NICELY encourage them to fix it. My motto is "Always be nice until it's time to not be nice".
