proper use of air shocks

I've had air shocks since a few weeks after I drove it new from the dealership.
I quickly installed them as that is what I used in my 62 Wedge.
Following the Mopar Chassis Manual, all we had, or needed back then was clamping springs, pinion snubber, and air shocks to preload, same as adjustable coil-overs now.
Preload pressure was in the teens, - however with the car loaded for holidays, towing a ski boat fulla camping gear, 4 people in the car, air shocks up to whatever needed to stop tires rubbing on corners.
Those air shocks ; (newer ones) are still on the car today and the shock mounts are just fine ! !
I'm sure somewhere on the East Coast there are rusted out POS that may have had issues with upper mounts, but I've let fear and common sense be my guide .
Cheers .
