You are correct. Some of the running 3 liter swaps are running only 19's right now, though I wouldn't recommend it. The '98 3 liters have the correct 24pph injector to run with the return fuel system, the newer injectors from the 3 liters have a different electriccal conector on them. Mustang 24's will work too, that's what I have waiting for mine.
