Torsion bar/shock options

I'm running 1" bars on my daily driven '73 Dart.
It has single adjustable Hotchkis shocks on the front and single adj. QA1 shocks on the rear axle. 7-leafs per side (2 LPG tanks in trunk)

But, I've just ordered a pair of 1.08" bars from Sway-a-Way to upgrade the springrate.
Sway-a-Way has one price for any bar-diameter, and they include new torsionbar boots and clips in the purchase.

Koni's are good. They come from my neck of the concrete woods. "Maybe" you want double adjustables.
For real (circuit)track-use I would even consider going up a few sizes in thickness.
