If it is really 19" from the front to back I imagine you will have a real hard time finding anything because 12, 18, or 24 is what those hoods usually are. If an 18" will fit though you can fairly easily find 2 36" long hoods that should fit. Will cost you a few hundred dollars though where building it (or having it built) will turn out much cheaper and look a lot better (as others suggested)
