Thanks for the pointers, I've actually not decided what guitar the pickups will go in yet, so any size or style would be fine as I'm gonna build it from ground up, did that with a tele, buying a body, neck etc and got a great result. Don't know if firebird kits exist but if they do may well go all out and try match that guitar, specially that finish, yummy.
So yer any pickup choices, or wiring points, greatly received.
