HELP:1968 c10 Upper control arm shaft

[SWINGSAX68]

Today I noticed a KNOCK KNOCK KNOCK KNOCK....from my front end....I get home and take a look....well the rear passenger side upper control arm cap is almost all the way out of the shaft. GEEZ....well looks like I'm gonna be replacing both uppers for now....
HOW DO I DO IT????? IS this something I can do myself with out any special tools???? I know I need to loosen the upper ball joint from the steering knuckle, do I need to remove the whole knuckle and drum stuff from the lower control arm as well????

Then I need to remove the shaft from the frame.....when putting on the new control arm shaft, do I just use the same spacers that came off with it????

Some one just give me step by step instructions...please...I think I can do the uppers myself...no probs...but I will take my truck to a shop and have them do the lowers.
