If you take a look at the top of an HR car where the panel goes over it is shaped.
And the front is half an inch higher than the back.
So when you put the front fixtures in the back is raised by half an inch as its not flush.
It is a different shape from a DE
I bought a completely flat one from fleabay made of carbon.
The seller said catagoricaly they fit the entire range from 2003-2009
When it arrived I had to reshape the front as it would not fit, and build up the back with double sided tape so it would fit flush.
Hope this explains things?
The reason I asked is I assume the picture in your post is of your HR and wondered how you got over this flush fitting problem?
If the panel is flat it will not fit my 2009 HR and I stil have the old flat panel in the boot to prove it.
Unless of course I have a micky mouse car ?
I will try to get some pictures up.
Where abouts do you live as if it's not far I will drive over and show you
