Suspension and handling upgrades for my Dart

•1" Torsion bars
•Quality shocks (KYB or equivalent)
•Full suspension rebuild with quality rubber bushings (Moog) Use Moog 7103 offset bushing installed to add positive caster
•Front and rear sway bars
•Alignment

I agree.

I think poly sway bar bushing are fine. Most aftermarket sway bar kit come with poly bushing anyway.

Poly strut bushings are fine if you cut the rear bushing down 3/16 so it doesn't hurt postive caster.

I think there is way more gain from Front and and Rear sway bars or 1" T-bars than Frame Connectors.
