What oil pan for Magnum Swap?

What oil pan are people using for their Magnum swaps? I have a 94 Grand Cherokee 4WD pan from a 5.2 Magnum. It's going in a 73 Duster with a 72 v8 K frame. Do I need a 360 LA A body pan?
Am I right to assume I use the pickup for whichever pan I end up using?
Thanks,
Jon
