I replaced the gasket with a new rubber one from Clark's, tightened the bolts according to specs (100 inch pounds) but the leak persisted.  Every time I checked the bolts they seemed loose, so yesterday,  I installed lock washers on each bolt.  Now, oil seems to drip only from the bolt farthest from the rear of the car, no matter how tight I made that bolt.  The other bolts seem to have stopped leaking, but you can see the dripping when you look under the rear of the car.


You shouldn't really need lock washers on the pan bolts.  And 100 inch 
pounds sounds a bit much for a rubber gasket.  I'd bet that maybe you 
have pinched the rubber gasket along the way and oil is getting past the 
split and exiting through the bolt hole in the pan.   If I was doing it 
I'd not use the rubber gasket with the cast pan.  I'd maybe go with a 
cork gasket or a heavy paper gasket.   I could see 100 inch pounds with 
a heavy paper gasket but not the rubber.    ...just my experience.


By the way, you usually need to snug up the bolts with a rubber gasket a 
time or two before they settle in.  But not 100"/lbs.
