Alright i used to have a perfectly good Jackson RR3 that i had purchased on ebay, until i got drunk one night and picked it up and smash the headstock onto the floor.

So, everything on it is fine, only thing is i need a new neck. but, idk the measurements or anything like that, i'm pretty much a noob when it comes to that kind of stuff. i was thinking bout ordering a custom neck off warmoth.com or finding one off ebay for cheap, considering I only have one axe now with no back up.

So, could you guys help me with figuring out the dimensions and how i need to find the measurements of it? thanks.
my guitar is a little bit older model.
i'm not sure the year on it but i could find out.
would that make a difference on size of the neck?
