These have no markings on them. I believe they were installed around 1975.The distance between the top and bottom holes is 5 1/4 inches. They are installed on wood, so I don't think the hole placement is critical.

I think you might want to look at SWISCO part number 39-074. Compare the measurements to see if this can work as a replacement.
