Front end suspension question?

[Redmond]

I bought a 77 stepside mid summer, the trucks been lowered 5 front/7 rear, well the camber is way out and I burned through a set of new tires extremely quick, I bought new tires, and took it in for a front end alignment, they said I need new ball joints, my question is, is there a certain type of ball joint that's better then others or that works well with a lowered truck, I know with my jeep moog ball joints are they way to go, they want to charge me 500 for ball joints that I can do in my garage in a couple hours, I figured I would do it my self, save some money, I just want to get the right parts. thank you for your time
