Yeah, torsion bars..... Mine are still from the slant-6 that blew up before installing the 318. Not too great handling.
Bought the car for $300 like 20 yrs ago. Drove the slant-6 until it spun a bearing. Then found a 72 dodge dart with a 318, took it out, put in Duster. Then cut up the old Dart and put it in the dumpster.
I bought mine for $300 back in the mid-80’s and sold it two years later for $600. It was actually a very nice looking yellow with that partial brown vinyl top. By today’s standards it was HUGE inside. Handling? Hey, it was rear wheel drive. I could drift! :-D
