Modding my ibanez grg7221

[Everyinchtheanimal]

Hi guys I'm looking at getting a new body and finishing it myself, but I was wondering does anyone know if the neck from my grg7221 would fit onto an rg7321 body? I've seen one cheap that needs some love and I'd prefer a proper ibby body to a custom one.
Any help would be greatly appreciated 😊
