Front suspension Q’s

Hey I have a 1966 Barracuda. I’m working on being more road worthy. I have some questions about front suspension. My upper control arms need to be replaced or rebuild, what are my options? Can I just buy the parts and have my local machine shop rebuild them? I did the Kelsey Haines brake upgrade a year or two ago if that changes anything. Also what’s the possibility of getting a front sway bar for an early A-body? While I’m in the front suspension is there anything else I should upgrade or replace?

Thank you for your help.
