The ARHS is looking to have new castings made of the Aluminum Step Treads used on A and B units. I can't find a drawing or picture of one at the moment, but if you own an E or F-unit, you should know what I mean. There were four per unit, they fit over the steel ladder top step and had anti-slip 'grit' included in the casting.

These have deteriorated from galvanic corrosion over the years, so finding an intact one is next to impossible.

If your organization is interested, let us know how many you need and then we can talk further with the supplier about pricing.
