That front is looking very nice, the same as Joe´s Alf GT in the background.
Looking at the D type nose on the right of the photo gave me an idea for the rear.
As Pharrell Williams says in his song "It might seem crazy what I'm about to say" so here goes.
How about using part of a front end to create a new style rear end?
It looks different but I don´t know if it has ever been done before.
Crazy or possible?
