Manual steering gear boxes use steering gear grease, not gear oil...which destroys the seals within a short time.
The reason for the leakage: The sector shaft seal (3591) and the steering shaft seal (3738) are history!
Both are available NOS and I suggest you replace the gasket (3581), sector shaft bushing (3576), steering shaft bearings (3571) and races (3552/3553) at the same time.
The above are basic part numbers. If you want the full part numbers and sources that have them, let me know.

C3AZ-19578-A .. Steering Gear Lubricant / It's grease, since it comes in a cartridge that's inserted into a hand held grease gun.
-------------------------------------------------------------------------------------------------------------------------------------------------
Column left, 18th part number from top:
C2AZ-19580-F .. Hypoid Gear Lubricant (rear axle) 90 weight. Same as C2AZ-19580-A except it came in a 120 lb. keg.

You can buy steering gear grease in any auto parts store, but before you use it, the seals should be replaced first.
