Help identify the bolts in Steering Box and choosing grease?

[funoldcarguy]

Hello, this is my first time adding grease to my 38 Ford streering box. I am looking for help identifying which bolts to use (I numbered them 1-4) and also choosing a type of grease. I am in rural America and have a Walmart and O'Reilly Auto Parts at my disposal, or if anybody recommends ordering a special kind I can do that too. Want to take best possible car of my truck.
