I have a 98 xj, and my comanche is currently down and not running for quite a while (long story) it is an 87 4.0L 2wd, and my xj is a 98 4.0L 4x4, i am wondering since my comanche has brand new calipers on it if i could interchange them into my xj since one of them is seized up pretty bad on my xj. I have looked them up online and i don't believe they are different at all, although they do have different part numbers. thanks!
