Schaller M6 Locking tuners

Can anyone with enough experience specify which tuners from this list are on the EBMM JP guitars?

Here’s the link:
M6 | Schaller

The specs for the BFR says M6-IND:
JohnPetrucciBFR6 | Guitars | Ernie Ball Music Man

I want to upgrade my locking tuners on the Sterling JP100D with schallers and want to make sure I stick to the original design, but with better tuners. I don’t know anywhere else to ask: should they be staggered or non staggered? I can figure out the screw holder angle by looking at the guitar.

Thanks!
