Older Mod.12-Thinking of taking it apart.

I have an older Mod.12,in 22-250,that i used to shoot in the factory class BR shoots. I have not had it out of the gun cabinet in 6 or 7 years! I got a lot of second places with it at the shoots,only beaten by a Sako 6PPC. The factory class dropped down to only me,at the shoots i went to,so i just quit going!
My Mod.12 has the big ole wooden stock and is heavy. Before stopping,i had put a new factory barrel on it.
I am thinking about taking it apart and turning it into a hunting rifle,in a 308 Win. I will just put a factory stock and barrel, on it.
To do this,what will i need,as to the trigger guard and stock bolts? Where can i get what i need? It already has a Rifle Basix trigger.
