Thanks Mike and Zedn. It looks a though I'll be heading down that track but I'll chase up some hot rodders first.

The big concern I have is that the rear spoiler is not attached to the boot lid as with most cars but does combine with the boot lid to create a gully right on the bottom edge of the boot opening. I reckon in one of our tropical downpours I will need something akin to house guttering - with a 4" downpipe through the boot - to dissipate the water coming in through the join!

Note; the gap shown in the photo will be narrowed to a conventional size.
