You need to take the measurement from the nut to 12th fret, and the 12th fret to the bridge saddles and see if they match. If they don't it won't intonate properly.
My Les Paul is 24 3/4" scale, measurement is 12 3/8" from nut to 12th fret, and from 12th fret to bridge.
This will vary if you have a different scale length (25.5" for Fender IIRC?), so measure the 24 fret neck first, then see if the 22 fret neck sits in the body pocket the same way, etc. so that the measurements match.
