help me find my oil leak

[1972BlueC20]

Hey guys,

I'm trying to chase down an oil leak......I've recently replaced my valve cover gaskets with felpro premadry gaskets and I've also replaced my oil sending unit both of which were leaking but they don't appear to be leaking anymore.

Here are pics of the oil leak, it's not really bad but I want to fix it


the oil is coming down from the back of the oil pan between the dust cover and oil pan, and there are droplets that form on the dust cover as well

any ideas where I should start or where you think the likely leak spot is??
