It depends on where you ask for it to be positioned, as it is possible to ask for it to be just beyond the 24 fret extension. And also what scale length you are going to use.

I would estimate the edge of the pickup nearest the neck would end up somewhere between a theoretical fret 25 to at most 27 which you get an idea of the distance at the below link.
