thanks guys! one of the reasons i asked is the rearend perches, when you put a 4x4 rear into 2wd you have to move the spring perches inward so that they will line up with the springs and that would tell me the 4x4 springs are mounted further apart? i would simply just measure but i don't wan't to drag home the whole blazer if i'm only going to use the rearend. thanks!
