Firebird versus Mini-hum sizes

[PitchShifter]

I know the two pickups are constructed differently, but how much difference is there in the sizing? Can I put one type of pickup into a pickguard routed for the other one?

I'm guessing yes

I'm guessing 'Yes' too. I have installed Firebird mini hums. into one of those P90 cutouts for the LP Deluxe Mini Humbucker.

Evolution neck pickup for sure. No question.
