I have got the hinge end sitting reasonably flush with the body but it required elongating the bracket slots a little more than they were originally, however the rear lip sits proud of the wings. The latch is held in place by 3 screws but there appears to be no adjustment, so is there supposed to be some?

Should be a combination of shuffling the latch mechanism up/down and the height adjuster screws along the perifery of the trunk edge.

That's my theory anyway.

I believe that he is talking about the 'trunk' lid, which has no adjustable bumpers. the front hood has those !!
The rear latch has some adjustment side to side and up / down, but not a lot.
Sometimes there are spacer plates under the L shaped bracket on the trunk lid. These can be removed to lower the height of the lid.
Did you install a new trunk seal ? This can force the lid up too high.
