Not too sure about in H-Town but I'd imagin Mitchell Race Xtreme could do it & do it well but probably not cheap. I've generally used Dennis @ Diffspecs here in Auckland, was in Manukau but moved out to Drury now so closer to Hamilton by a little bit, never ever had any drama with any diff or auto trans work he's done & he does a lot of NZV8 & NZV8ute stuff.
