I don't see any wetness around the pan sides, so I'm guessing that's where mine is too. I have looked from every possible angle and it appears to be a sepage at the bottom of the curve.

FWIW, often times the seal will wear a groove in the hub. If that's the case, even if you replace the seal it'll still leak. You can buy a thin sleeve that goes over the hub, or you can buy a new hub for ~$50.
Here is my high-tech seal installer:
Here it is in use:
Other leak locations on the LT1/4 engines are the optispark seal and the waterpump driveshaft seal (both in the timing cover), and of course the intake manifold gaskets (actually RTV is used for the front and rear of the intake).
