I can line you up with a guy that can sell you one fitted and certified for around $2000-$2200. Aussie made. Mine is a 2.5tonne but the 3tonne examples are around that price now. He is Hunter based but i'm sure he has collegues in Melbourne.

I forgot to mention, did everyone like the innovate way to hold the engine to the car without the box in place? 1st and 5th photos. Worked beautifully and didn't damage the original paint on the sump! And was stable as a rock with me jiggling the engine around removing and re-installing the exhaust manifolds (as the studs snapped off) and also the flex plate and welch plugs. Banging, prodding, twisting etc and it stayed as solid as a rock! I tell you what though, with one of these with air and steer, you would NEVER get the exhaust manifolds off without a hoist, an air ratchet, 2 x extension sockets and lots of swearing! That or pulling the whole top end apart leaning over the engine bay. From underneath it was tough, but no stiff back or neck or chipped paint.
