What diameter torsion bars?

I must add that when the new 0.940” bars were installed, I also installed six leaf rear springs at factory ride height, and sub frame connectors. My car does not have air conditioning or iron manifolds, but is equipped with KH disks & power steering, so the slant loaded front end is on the light side of all things Mopar. I do not run a rear anti-sway bar. Car is well balanced, dose not under steer, or want to let the rear hang out on dry pavement.

As a few have said previously, it depends what spring rates one needs on what you use the car for. My set up is for touring-daily driving and no serious drag racing. When I got the car it was a former drag queen that completed four winning seasons at Englishtown, NJ. in the nineties, built for the strip with mismatched torsion bars, and super stock springs. I could hardly keep it on the road, it was a death trap over 30 MPH, and handled as if the was a big hinge between the front & rear seats.
