Changing shocks absorbers - '72 C20

[emil77]

Hi guys,

My '72 C20 bounces around alot. I know it's the nature of the truck to have a rough ride, but I think changing the old shock absorbers will help.
How hard is it to change the shocks, can I do it in my garage? I have to change the shocks at all 4 corners. Is there any recommend brand?

Advice, comments?
