Extra bracket on rear leaf spring

[Neblazer71]

I have been looking over and taking pics of my recently purchased 71 k5 and am full of questions of course.
Here’s one for a more educated member, on the drivers side rear leaf there seems to be an extra bracket that really looks like it does nothing and there is not a matching one on the passenger side..what gives?

Thanks for any answers

The only way to get educated is to sometimes ask dumb questions.
