the sherpa engine should have what's basically just a tin plate covering the front of the timing case. but as you say, you can't really see in the pics cos the battery is in the way.
and the timing case itself is a different shape, meaning the injection pump is mounted higher up, which in turn means you don't have to alter the chassis engine mounts to fit it.
if it's a 2.5 n/a out of a defender, then the injection pump will be lower down and the drivers side engine mount will have to have been cut off the chassis and replaced.
