You can make any warmoth guitar with a 24.75 "conversion" neck, except mustang, jagstang, and jaguar. Those bodies are dedicated 24" scale. The body and bridge placement is the same, only the neck needs to be different. Mix and match.
The 7/8 scale strat is a dedicated 24.75 scale 24 fret guitar, I don' think it's compatible with other warmoth parts. But they have something in the works regarding this, you might want to call them up to get info. They have dropped some hints around though.
