RO1320 is the Green bezel Ceramic Sub with the correct case. They claim this one has a gen ETA and looks like it, though it could be one of the new super clones.
RO1187 is the ceramic sub on the RWI list with a clone ETA. Make sure you get the clone ETA so the dial which match up to the ETA from the Green sub.
I did not try to swap crystals but I think (can't recall) that they may be different sizes.)
To Sum up what you Need:
From the Green Sub RO1320 you will use:
The case
The bracelet
The Crystal (have to relocate the Cyclops)
The Hands (or at least the hour hand which needs to be relumed)
The larger round markers from the green dial (it has green lume so they need to be lumed blue)
From the Noob RO1187 you need:
The Clasp (swap it out - two screw pins)
The ceramic insert (easy to get out if the crystal is out)
The Dial
The Crown (if you can get the stem out - noob has a better crown)
One could use the noob dial with out modding it, and just have the hour hand from the green sub lumed to match noob lume (watchlume mix of SB blue and Aqua Blue works great).
Stripping the lume from all the markers and hands and doing the pearl to match is worth the effort IMO. So is painting the base of the markers and pearl white gloss enamel (testors model paint). It makes the lume brighter with a slight whiter look too it which appears to be more gen-like. And the markers themselves will look a nice white in day light. This is important because if using luminova, or any bright blue lume, the markers get a kind of blue cast to them due to the intense glow in any nominal or low light situation (even indoors under fairly bright light I noticed this. I also painted the lume on the back of the hands after the lume dried. Just a light coat of white. It helps the hands keep up with the markers in intensity and I noticed from some lume shots of Genuine Ceramic Subs and the Deep Sea they don't exhibit the reflective glow from the back side of the hands like some older model Rolex watches did (often in lume shots you could see the dial illuminated from the glow of the hands). Tri-tec recommends the white background so I will assume Rolex is using that method now given the images I have seen.
