Replacement Meco Regulator / Fisher Control Valve

I have an old safgas CNG system that still works well, and I have a source of CNG. However, the primary bolt on my Meco regulator is beyond stripped at this point and I need to replace it, it's fixed to the part so I think the whole assembly needs to be replaced. Essentially, it lightly leaks CNG under pressure when the tank is on, above ~1500 psi, but for obvious reasons I want no leaks.

Does anyone know of a good replacement to the Meco regulator and control valve? Is it possible to change the stripped bolt, or get a better seal so that it doesn't leak when the bolt is fully tight?

Thanks for this, have found a few used ones but I was hoping to find a modern replacement equivalent, I Don't know the first thing about CNG systems but I would bet there is something out there that fits the standard thread? I'm not sure what that would be

Unless you find someone that may have done a recent replacement finding a suitable CNG regulator to use with a portable (boat or RV) system could be a shot in the dark. I would consult with a CNG technician as they may know offhand which modern regulator would be suitable. The best options would be to call the Gas Company in your area or a Distributor or Retailer for Gas fittings, welding and components. Good luck.
