Just and FYI, all the wizard necks from the 540S or original 540P guitars are 22 frets and fit a strat perfectly. A non-AANJ wizard from an RG also has the same dimensions at the heel, but you have to saw off the extra two frets, and usually, depending on your neck pocket size and pickguard, shave off the extra maple reinforcement they leave under the fretboard. But nothing else is altered. The scale length is the same, and the location of the neck mounting is the same on any non-AANJ wizard.
Few necks will tolerate being carved down to a wizard profile. Warmoth never used to do it, and I've heard that its a hair thicker than an original Japanese Wizard. Their dual truss rod is a bit thicker.
