The D-Act X uses blades, so there's no poles to line up. You'll be fine.
If you need to get a pickup with pole pieces, PRS uses a 52mm spacing - a bit wider than old-school Gibsons (50mm IIRC), a bit less than F-spaced (53mm). I'd go F-spaced for the bridge and standard for the neck just for coverage, but either will work.
