Duster rear suspension issue

No kidding, I wrecked a 74 dart in the early 80's due to jacking the rear
up with air shocks, only took a couple of weeks to punch a hole through
the trunk....

Really? 20 years with airshocks on my Cuda and never a issue. I was just under the car yesterday putting the driveshaft back in. (Raided parts for the Duster.)
