4.0 ZJ in a YJ?

Do all the 4.0 jeep motors have the same bolt pattern for the bellhousing? In other words will a 4.0 out of a ZJ fit in a YJ?
93 ZJ motor.

Sure, that is if you're bolting it up to the AX15 tranny. If you're trying to bolt this up to the 4 bangers AX5 tranny, I'm not even sure if there's an adapter. I know AA doesn't recommend using that tranny. Considered too light duty for even the 4.0.
