are you sure it's seperating, or did someone fill it and the fillings coming loose. i don' t really see how it could seperate? of course i'm drunk and not thinking straight, but still..there's no pressure to the outer edges (except the hooks, but that's negated by the hood pressing against the apron).
they look good with the seam in the middle. i've got a late model hood on my 40 now (it looked good, so i put it on, then i discovered the bondo)...i hate it...it's just not the same. i even put the chrome strip on and it's still not the same. split hoods rule!!!!
