Re: 1972 gmc recall
The recall concerns itself with the front spring's left shackle stop being improperly adjusted, not the shackle.
The shackle stop is the L-bracket bolted under the frame directly behind the front spring's shackle that, in the event of a spring break ahead of the axle, is meant to stop the spring, axle, and frame from collapsing rearward which could cause the steering shaft to send the steering wheel into the driver.
