Okay, a few photos.
I got a grease swivel. I put a 1/8" NPT zerk on it so I wouldn't have to unscrew the locking one from my hose, just clip it on.
But that was still too long. Looking in my assortment of zerks, I thought of another approach, just put a 45 fitting on the back of the grease chuck. Could have saved myself the cost of the swivel, but now I have one if I ever need it, and can remember where it is. (Replaced the front wheel bearings in the truck a month ago, just found the bearing packer this week. About time I learned to pack them by hand anyway.)
Revised and shortened:
This fit nicely
Steering arm
Not great photos but I think you can see where the arm was put back on, next to the spindle, and the little angled piece to hopefully make it break somewhere else next time.
I noticed that the spindle bushings in the beam move forward and back some, I think I will put a couple of heavy tacks on them to take out the play. Will probably have to clean the grease and oil off them first, weld, then put new oil back on.
