Looks like the OP means 767-300, at least according to the DL timetable for that flight. FWIW, according to Seatguru, DL does not even have 737-300s, I don't think they would have the required range if they did, and row 25 would not be an exit row in any DL 737 I have flown on.
Again, according to Seatguru, the 25 AB and FG seats don't recline, but the center section has not such remark.
