That one looks really kool to me !   May be it's just because i've planned something very similar for my 40 delivery, kinda hardtop delivery, but with kustom treatment !  
 
May be you could pull a early Vette grille in that mouth just like i did on my 'vert ... but V-ed to follow the mouth.. 
 
  
 
Sometimes, what kill a project, it's when you think of a very sweet  '40 , something with coatchcrafting spirit, sectionned, with strongly reworked fenders , something may be Westergard could have done, and you ended with....a goofy 40  :shock: ! something that don't look kool from any angle !  :cry:
