sliding bottom rail pivot

I have older Benchmark doors and I need a couple of the sliding bottom rail pivot bracket. The part that the bifold pivot pin goes into. There is one on the top rail that has a place to screw into so the bracket can be used as a non-moving hinge bracket.Not sure if the same bracket is used as a sliding bracket and a non-moving hinge bracket.

See attached photo.

Thanks for your help,
Joe
