I need your input, sorry, not Mopar related

Make sure the leak is actually coming from the rear main before tearing into it, you'll see oil streaks on the flywheel. It could be leaking from a valve cover or the back of intake manifold. If it turns out to be the rear main seal put a rope seal in it, these will seal just about anything. While the pan is off I would throw a set of bearings in it as well.
