Difference in CJ Vs YJ 4.2?

Obviously they're both carburated 4.2L 258s but is there a difference in anything that would preclude someone from putting an older CJ (1984) motor in say a 1990 YJ? I heard a rumor that the starters are different, would that mean the flywheels are different? If the tooth count is the same then shouldn't either one work? What about transmissions, will an AX15 bolt up to an '84 motor?
