If it does prove to be the front main seal, there are two things to look for. First, a small groove worn in the crank nose from 43 years of rubbing on the seal. There are things called 'seal-savers'- a thin cylinder of steel that slips onto a worn crank nose and Lock-tites in place. They are cheap. Second, a previous owner may have installed a 351-W front seal. This is identical to the Cleveland seal EXCEPT it does not have a flange that positions the seal properly in a Cleveland. A Cleveland seal installs from the outside. So the Windsor seal in a Cleveland cover simply floats in the factory hole and may move. In a Windsor, the aluminum front cover regulates where the seal goes, but you have to install it from the back. On Windsor engines, I bore out the aluminum cover and use a 351-C seal so it can be installed from the front without teardown. Many Parts Stores will try to tell you the two seals are interchangeable; they are not.
