I was wondering, is there more than one kind of drive axle setup in the '79 280ZX? I need to replace the rear axle halfshaft, and mine is the kind with u-joints on the ends and a cv joint in the center half of the halfshaft. But when I went to Autozone today to order a new one, the picture that came up for my model showed an axle that had cv joints at both ends of the halfshaft. Could they maybe just have had an "example photo" in their computer and just not one of my particular halfshaft?...Or did I order the wrong one? The one that came up was the only one listed for my year and they said it was the right one....Any ideas?
