Raising the rear end

... and air shocks will rip out your upper shock mounts.

Not to debate, but I've run air shocks on my '65 Barracuda for decades to keep the car off the tires. Nowadays I use 40 psi or so, but in the old days I used 90+ psi on a daily basis. I have never "ripped out my upper shock mounts". In fact, there is no sign of deformation or anything going on with those mounts. I'm just sayin'... it's an option.
