1974 Duster build

DionR,
I actually went with the QA1 shocks. Lemme say, MUCH better.
I was using KYB shocks, which was good with the stock torsion bars (.89). But once I put the 1.03" ones in that combo rode like a tank.
Here is the shocks I used:
(front) QA1 TN501 QA1 Stocker Star NA Shocks | Summit Racing
(rear) QA1 TN901 QA1 Stocker Star NA Shocks | Summit Racing
She now rides slightly stiffer (vs. the .89 bars and KYB shocks) with all QA1 goodies and 17 inch rims but handles awesome.
Let's just put it this way... she handles MUCH better than my old 2006 Honda Accord V6, when it used to be opposite when it had the more stock setup.

The lower control arms are the only part that is left original in the front suspension. It's been welded/reinforced of course, plus with a bigger anti-sway bar from QA1 installed as well to help things out.

The rear is going to have newer stiffer leaf springs and a rear anti-sway bar installed later on.

Nice!

KYB where ones that I heard specifically didn’t work well with bigger torsion bars, so makes sense.

If I had a faster ratio steering I would put my Duster up with my old Challenger, so I agree these can be wonderful cars to drive with some simple upgrades.

That 408 should be nice when you get it in the car.
