Second stage really should just need a 014 o ring (inlet fitting) and a basic puck soft seat (I punch my own from sheet silicone). That generation second you really want to look at the plastic around the inlet fitting for cracks, though.
I'd look at the VDH manuals and catalogs link for a service manual for the first stage.... Looks to be an externally adjustable flow by piston. 3 o rings and a the seat (which my be able to be flipped).
Edit to add:
I've seen 2 references to the Pro Diver firsts, one is a cutaway image that shows what I described above. The others describe it as a funny shaped Conshelf (for lack of better words), in which case a Conshelf kit would do it.

I’m pretty sure this isn’t a piston regulator, but an update to the Conshelf design, and from my memory done the same internal parts as a Conshelf (balanced).

The ProDiver Royal is definitely not a piston regulator. I just ran through the parts list for both it and the Conshelf, and they share quite a number of parts. The parts they don't have in common seem to be more due to the size/shape of the ProDiver Royal 1st stage.
Given the different iterations of the Conshelf, I am not sure if the ProDiver Royal was an update as much as it was a lateral one-off type design. Given the shape, I wonder if it was the DNA precursor to the old Titan, which I believe also shared internals with iterations of the conshelf.
