Funny...I was just working on some gear that looked like that.
In my task, I was hindered by the little detail that the maker had stopped making his Fine Pieces of Engineering. While I was able to locate the breakers I needed, I was not able to obtain the necessary hardware.
So, in my case, I spent a pile of money having a machine shop duplicate existing hardware. Not only did I need plates like the one fabricated here, I needed aluminum standards for connecting the breaker to the busses.
This gear, btw, had 1/4-20 bolts as the typical connectors.
