Original A body 8 3/4 housing

Spring perches are a pretty decent hunk of metal; can you expound on why or what caused one to rip. For example if the vehicle was damaged in some way that caused issues with the rear end/perch, I as a prospective buyer would want to know the why's since it was brought up that the perches were replaced. $350 is a pretty good chunk of change for those of us that watch our pennies. Thanks for your understanding and comments.
