You will need either a 360LA "car" pan or a front sump pan for a Mag. Not sure what that would be. The pan is a change for the magnums. Mags whether 5.2 or 5.9 both use a 360 type pan, IE has the smaller rear cutout.
That's the "center sump" pan and can be gotten for about 50 bucks pretty much anywhere.
I think I paid right around 75 for the pan and matching pickup.
