Re: 1970 SS 396 Chevelle: My first job!
Damage to the upper rear shock mounts was somewhat common, in the 70's. It was often caused by guys lifting the back of the car with air shocks, to make room for huge tires.
The weight was no longer on the springs. All the body weight was on the shocks, so it started tearing up the upper frame shock mounts. It was a problem with El Caminos too, because all Elkys came standard with air shocks.
The air shocks should only have about 15-20 lbs of air in them. Back in the day, the higher the better, so they often got 100 lbs.
