Steering Column: Seeking assistance identifying some parts, etc.

[71CHEVYSHORTBED402]

1971 C-10, Automatic Transmission and no tilt wheel.

I need to remove the entire column, and at some point the steering box as well. I have a manual, but I'm a bit lost at the moment. Could just tear into this, do it wrong or break something.

I've only removed what you see missing in these pics, and the bolts from the rag joint to the flange have been removed. On a side note, I don't think you're supposed to remove those rag joint to flange bolts. The book says to remove the nuts and then "lower" the steering box to replace that joint, which seems to mean the bolts remain in the joint.

Any suggestions for procedure appreciated. Anyway, these pics are self explanatory with questions, and an image of the parts list from the manual are included.......Thanks for any help.
