Help? Can I use a 2x4 engine in a 4x4?

[jmarshall09]

I have a 1998 4.0 liter 4x4 ohv extended cab Ranger, and need to replace to the engine. I've found a good deal on a 1998 4.0 liter two wheel drive engine and I'm not sure if the 4x4 and 2x4 engines are interchangeable? Any help would be appreciated, thanks.
