Custom Rolex dial makers are required by copyright law to use a genuine Rolex dial to start with, then it gets sandblasted to a blank. I doubt that all of them do, I'm sure there is a lot of repping done in that niche business.
But to keep their actions less obvious, they will want to make your dial the same diameter as a gen, with feet in the 3136 movement positions at 13 and 37 minutes for the 116x model, or with friction fit rims and no feet for the 3235 movement 126x models.
The 2824 movement is much smaller than the gen movements, so what rep factories do is use a DJ41 dial with feet in the ETA positions at 12 and 42 minutes but the feet don't go in the movement they go in holes in the wide movement holder.
So whether you want a 116x or 126x style dial, if you ask for feet in the 3136 positions, it's likely you could just drill new feet holes in the ETA movement holder and be done with it. Even if they were willing to put the feet in the ETA positions, there is no guarantee they would match up laterally with the ARF movement holder holes.
This is a BP DJ41 2824. You can see the dial feet at 12 and 42 minutes, and the feet holes in the movement holder next to the tape I placed as dial spacers.
This is what 126x 3235 DJ41 dials look like on the underside. To use one of these in an ARF, the movement holder would have be notched (a lot), or the rims grinded off and new feet glued/soldered on. Both are possible and have been done by members here, but using a 3136 dial is simpler.
