I believe it is called the Steering Shaft Oil Seal #350892R91. I'm pretty sure you can get it at NAPA or similar. It is an easy replacement by removing the steering wheel and support bracket, then remove the 2 bolts holding the Steerig Shaft Bearing (where your leak is). Slide the unit up and off the shaft, press out the seal, clean the retainer and install the new seal with new gasket. Your steering shaft looks smooth, but make sure you grease the seal lip to avoid damage. Also, it will go down the shaft much easier if you put a piece of plastic (strip of ziploc) inside the lip.

If you haven't already done it, make sure the steering housing filler plug VENT HOLE is clear. It goes from the bottom of the plug, makes a 90 degree turn and exits out the side. This allows venting as the steering gear housing gets warm, and if it is plugged, gear oil may be pushed out the seals: shaft AND worm wheel oil seal, which is on the bottom.

I think Dale gave you a Cub answer but you need a Super A answer. The main difference is there are no 2 bolts at the seal. You would remove the shaft out the front, where the big plug is.

You need to remove the steering wheel and remove the giant plug on the front. The whole shaft comes out of the front end after you rotate the worm off of the gear. (by simply turning the shaft) I removed mine before simply to get the steering rod out of my way when I worked on the engine.

Aaarrgh!! You are absolutely right, Jim!! Thinking too much about Cubs right now!

Here are a couple photos of the steering gear housing when I was rebuilding my '48 SA. Maybe these will help. Let me know if you need more photos!

FYI, it was a lot harder to reinstall the steering shaft than remove it! Also, the large "nut" on the front needed some tightening several times to stop it from seeping. Takes quite a large socket, but works better than a wrench, since the flats are slightly tapered.

got drain plug lose and as mentioned a lot of water came gushing out first followed by black goopy oil -- anyhow I have 1 1/4'' socket on the plug that you need to take out in order to remove the shaft and with breaker bar it feels like I am going to bust the cast iron before I bust the plug lose...I am wondering if I can put kerosene in the steering gear reservoir to help break down rust? free that plug?

also in regards to making sure the "steering housing filler plug VENT HOLE is clear" as you can see from the photo below my filler plug has a strange piece of tubing on top with a mini pipe clamp holding it ,,,whats going on with this?

You won't break it. I recommend spraying something like WD-40 around the plug and letting that sit for a few minutes. Mine was pretty damn stuck on there the first time I removed it. Don't be afraid to man-handle it. Its a solid cast iron piece that you are twisting, its not like you're putting impact forces on it and its not like its a bolt that will just shear either.

As for the vent cap, I have no idea, look like a farmer fix. The normal one should a simple square headed plug with a small hole in the side. (Similar to the oil level check plug on the transmission)

here is the plug - perhaps it would work if I just knock some paint off the black hose or put some slits in it for air to escape? the hole on the plug itself seems too big to just leave open especially as it is straight up

A vent hole is a vent hole. I would suggest putting a small elbow on it because having it straight up means water can more easily find its way down into the box.
