Will new torsion bars correct that POS, bucket-o-bolts feel I have?

I upgraded my bone stock '73 Dart with the following items which made it pretty much handle like a modern car;

- Hellwig front swaybar
- 1" Torsion bars (Want thicker bars now)
- Modern tire alignment with more caster with help of MOOG offset bushings.
- Borgeson powersteering box
- Reinforced steeringbox mount
- Welded in homemade subframe connectors (made the car quieter and feel more solid)
- 17" Aluminium wheels with 50-height tires.

My Dart also had slider type calipers which made clunky rattle noises like something was about to fall off the car at times.
After the upgrade to pin-type calipers this went away completely.

Personally, I would start by loosing your 14" wheels and too-wide tires and go at least to 15" aluminum wheels with a better brand tire. This will smooth out your ride.
Install welded subframe connectors. This also will remove some of the body rattles.
Lower the car about 2" and upgrade the torsion bars AT least a 1" bar.
For my dailydriven Dart I would like to go to 1.06" or 1.12".
