Would an Original Floyd rose nut fit on a standard strat neck without modification?
Short answer: No. Long answer: When you say, "standard strat neck", do you mean a neck that has just a slot for a standard plastic/bone/tusq/corian/graphite nut? If that's the case, then your neck WILL need to be modified to accommodate a Floyd Rose-style locking nut. The modification includes the drilling of two mounting holes through the back of the neck and the making of a "shelf" for the nut. Warmoth has some great info about this on their site.

If, for your first guitar building project, you're planning on having the neck custom-made by Warmoth, they can do the Floyd Rose locking nut prep for you at their factory. If, on the other hand, you're planning on using an already existing neck, I would recommend that you take it to a
very experienced guitar repair technician or luthier to have the modification done. Don't try to do it yourself.
Oh, one more thing. Welcome to the forum.
