HRO SYSTEM 9 Parts?

[SV Demeter]

I know this is an old unit but does anyone know where I can find parts for this watermaker? Looking for a new control manifold. The place where the diverter valve attaches is damaged and leaks. There was a small threaded boss in there but it stripped out. There are ways to Rube Goldberg it but would prefer to find new parts if possible.
