I'm not positive on the screw hole alignment - probably is the same - but I'm positive the pockets themselves are the same. The old IBZ heel is based on the Fender. Of course with the over hang on a
Strat body you will have to move the
neck pickup or cut two frets off the neck.
The thing that puts me off Warmoth is to get Wizard profile, 24 frets, straight 16" radius, locking nut cut, and angled headstock to replicate an Ibanez neck it's almost $300, and I've picked up complete old RG's for less than that. So I usually take my chances on ëßãÿ for the real thing, because it will be less.
