Just avoid the 24-fret necks as you'll need a body built with an appropriate extended heel rout to fit them (and the humbucker routs closer together), otherwise the bridge position will be out by 20mm or so. Stick to 22-fret necks unless you know your body is built for a 24-fret neck
I wondered about that and was planning on doing a 22 fret neck to avoid any problems.
Looking at the photos of the pitbull bolt on necks it's hard to tell whether they are deep enough to fit this body. I'll try to take a photo and post tomorrow to make it clearer.
