Square making a turn?

[KMARSHAL]

Hello , I am looking to improve the handling on my old 86 it’s a swb 2wd no factory sway bar , my first idea is to put all new bushing in the control arms and install a sway bar I’m wondering what brand bar and bushing should I bee looking at the truck is its stock ride height, and (I would like to keep it that way) with 15x10 275,60 tires all the way around , and if a rear sway bar is worth the money, any incite would be greatly appreciated
