MOPAR engineers were very good, they didn't add anything that wasn't necessary. They looked at the loading and as mentioned above they saw the bar wasn't going to go anywhere. So just a clip was OK.

Crashworthiness? Get real. When the torsion bar front ends were designed the big safety features were door locks that wouldn't open in a crash. Seat belts were an option if you could get them at all. Steering columns would spear you. Crashworthiness was far from top of the list and if anyone gave it a thought it was to make the car more resistant to crumpling. Energy absorption and controlled deformation were decades in the future and really only occurred because of the government.
