Coin slide replacement help

[ACTcarwashlover]

Hey guys, I’ve got an old piece of equipment that I want to put a new coin slide on, I have tried an ESD coin slide, but due to the metal cutouts on the inside of the coin box, it doesn’t physically fit, it used to use a single comet token slide but That was long gone,
I’m hoping that someone could probably either have one of those spare or even suggest a Modern replacement for it, I have seen the model 444 from Monarch but I don’t know if it’s compatible
