9" Ford Leak

I'm finding a small leak of rear oil behind the pinion. I'm pretty sure it's not the front seal around the pinion and I tightened all the nuts around the 2 front gaskets. The rear has about 1500 miles on it and was supposed to be new when we bought the car.
Anyone have an answer?

I was getting the same thing, the pictured rear end has about 5,000 miles on it in the bird, after gear change did not leak.

Then it dawned on me I had bought a new bottom plug after about 3,000 miles because the other was looking bad and just happen to remember one day to pick one up. Could not stop it with tightening so took it out and put tape on threads.
No leak.

Its always something stupid.

After a drive it was smeared all over so could not tell, but clean up case with rage after a few days my plug had a little oil hanging off it. It would leave a 2" spot after a week of setting.
