moog k772 vs uniball

hey max , couple questions if you could answer . i am having upper and lower control arms built for my 1962 mercury comet , i was planning on running uniballs , but have been told recently that the k772 chrystler screw-in style ball joint has 32.25 degrees of articulation in each direction which is the same as a uniball ,,,can this be right ??? i am leaning towards the ball joint only cause of limited space in my wheel , i am only running a 20 x8.5 . the car is body dropped to the rockers but with a total diameter on the wheel of 25.53 inches , i don't think i am going to need 15inchs of lift , thanks in advance ,,,i figured you have been there and done that to most of this stuff
