I have a complete a12 that I just ripped out of my car, with oil pump, alternator, fuel pump, manifolds. Its kind of in pieces but I can put it together if you want but would probably only be suitable for a rebuild. Also have a carby on the manifold, its a bit dusty but cant see why it wouldnt work.

I am keen to clear the stuff out and I am also in Adelaide so if your interested let me know and we can work it out.
