I just found quite a few used and N.O.S. Grease cups
same size as the drive shaft cup but threads are same as rear axle and steering, any one know the application or cars this would have been used on the head is slight different see pics, Bob

That would be the '00' size grease (or dope) cup. 1" case for holding 1/2 oz.

The '1' is used on the universal joint.

Lots of cars used these, just generic. These are Empress brand, the most famous. The ratchet type were spec'd by Ford for the Fordson and TT, to keep the cups from twisting off from vibrations. Many times you can find the ratchet type on the T.

The driveshaft has larger threads, cup is same size though, so these will work on rear axle and steering also ?

If the pipe thread fits, sure. There is lots of space for the larger cup size at both places.

In fact I run the larger size cups on the rear axle Hyatts to make greasing go quicker. Two full caps instead of three or four little stock ones!

IIRC, 1/8" NPT on axle brg and DS bushing cups, 1/4" NPT on UJ, both sizes shown in Dan's examples. jb

Yes but all the ones I found are 1/8, if anyone needs some let me know most look like NOS, But have not opened them up, Bob
Just looked again have both sizes, cool

You can sell those by the pound! Golly boxes of 'em!

Here is a larger cap size for more grease, it has the 1/8" pipe thread of course. Put one on the steering column bushing too, can't have too much grease on the Ford Besides, with the larger cup can go 1,000 miles between greasing the Hyatts from the factory recommended 500 miles

Larger size dope cup on rear axle Hyatt bearing spot, compared to the stock size Ford used there.
