72 Duster New torsion bars what size?

I didn't have any issues getting back to the stock height with the1" Just Suspension bars on my Duster. PST makes a set of 1.03" torsion bars, and although there was some complaints originally about ride height they changed the indexing on their new ones, so they should be fine now. They're also a site sponsor so you can get a discount. Firm Feel sells 1" and 1.06" bars, they're also a great vendor. That's where I got the 1.12" bars for both my Duster and my Challenger.
