Thanks for clarifying.
AND, this would be good news as well.
I reviewed that and several related posts.
It looks like I misinterpreted when you said 'it' in post 4314, and which pickup you meant in post 4322.
We should put together a complete list of which Mustangs' stock and aftermarket pickups have which characteristics, regarding magnets' polarities, direction of windings' wraps, and external connection polarities, as there has been significant misunderstanding, confusion, and/or just not knowing sometimes, about them.

Regarding the
Nordstrand NM4 pickup in particular :
NM4 Mustang Replacement
I was unaware of that pickup until now, and have just looked at the page.
It does not seem to mention anything regarding what you have learned about the magnet polarities/directions.
Also, it states that the NM4 was designed for the
MIJ/CIJ reissues of the Mustang bass, which ironically is one of the models which might least need it, as those already have that design of pickup [internally like a P], and which apparently are slightly larger externally than most other Mustang split pickups.

As for the
Squier VM Mustang bass having the better design of split pickup too, I did not know this, so thanks for researching and posting about it.
That said, it is further ironic that a low end Mustang would have the better design of split pickup, and the current most expensive model(s) would have the poorer design.
Go figure.
