the baffles & windage tray are used together , the baffles stop the oil sloshing away from the pick up tube during acceration & braking , the widage tray removes oil from the crank & keeps the windage from the crank from foaming or lifting the oil inside the pan
Not sure on the differences between the part #s , even Mopar doesn`t seem to know as the volume of that pan changes in the different catalogs from 5-6 qts
