have a 1977 F-150, 4x4 with 79000+ miles on a factory rebuilt enginge. There is a slight oil drip coming from the bell housing inspection plate area. I also only have 10-15 lbs oil pressure at normal temperature idle. Is this indicative of a worn rear main oil seal? If it is, will "Bar's Rear Main Seal Repair" correct this problem?

A rear main oil seal will not have any affect on oil pressure (unless the leak is so bad that oil is dumping out, obviously). 10-15 PSI at hot idle is just fine; the rule is 10 PSI per every 1000 RPM; so assuming your idle is at a decent speed, you're at about twice the minimum. The idiot light in the dash typically comes on at 5 to 7 PSI.
I don't recommend any sort of "stop leak" product. They rarely work, and often lead to other problems.
