440 Dart cooling fan & shroud

have you looked into the HHR fan setup? I hear they fit great on a 22" radiator and flow a butt load of air and are pretty reasonable as far as cost goes. Dont know how deep they are though.
HHR fan assenbly looks great as far as outside dimensions, but it's 4-1/2" thick. I don't have the room.
I dunno WTF I'm gonna do here.......
