To answer my own question, yes it does fit, we'll nearly...
Having removed various ancillaries it was still a long way off. So as expected the throttle body and primary inlet casting was removed. Now it's just a case of fine tuning a few high spots and shortening the dipstick handle. In the photo below, the two rectangular plenum openings are where I will mount the new 48mm Jenvey throttle bodies. Will also have to reposition the oil filler. The power steering pump is fouling on the unused engine steady bracket which is preventing the engine from sitting correctly on its mounts.

That's the important stuff. If I keep the aircon compressor, it's inlet/outlet manifold will have to be modified too.
