My 65 convertible had a bad pinion seal that dripped occasionally on local
driving, but on the highway it caused an oily streak under the differential
and caused oil film on the rear lower bumper from the turbulance of wind
going under the car & out the back. That was the only leak under the car.
New seal cured it.

carrying it to the back of the car. That is where it gathered and made a big
mess. Looking under the car did not seem to reveal anything out of the
ordinary, except the spot where the oil was actually dripping from.
