It all depends on how fussy and realistic you want to get, the wedge would be perfect, but if that is out of reach, i would grab one of the many Hemi's available in various kits, grab a tunnel ram from what ever you have in the spares box, and modify to suit. Personally, i don't thing "correctness" is all that important, as long as it looks good, and reasonably right i am happy. ( nothing against those who do like things perfectly correct either).
