OK I will chip in with my bit. I ordered the car from Morgan with a leather covered cowl. It is better but, as you can see from the photo that Clipper posted, there is still a gap. I don't particularly like the metal solution and I think Shiremog's is better.
This subject has come up before and you can see the thread
here from that thread
Have a look at Allon Whites website...he does a leather covered replacement with a face to cover the gap.
You can see their solution in this photo.
