I finally got around to changing the pan gasket. A two hour job turned into an all day job because I decided to clean the outside of the pan and repaint it. Since I had to wait for the paint to dry I lowered the rearend 3/4 of an inch so the car sits more level. I don't think the pan gasket leaks at all anymore but something is leaking between the transmission and the engine still. It drips out of the little hole in the flywheel cover still, is that a rear seal? At least I got to clean out the pan, although it wasn't as dirty as I expected.
