I have installed the front and rear leaf springs and shocks Rough Country 4" lift on my 1977 CJ5. I have left sway bar extentions. I have drums and power steering. The photo with the install instructions show discs. Am I supposed to have a sway bar? What benefit would it serve? Can I order one with drums? The whole reason I went with a lift kit was because I had some POS shackle lift. I'm gonna start a new thread with pics reagarding that. But, should I be concerned about not having a sway bar on a manual transmission, power steering 1977 CJ5?
