What's vitally important here is year. There are several year generations for the clusters, and they are not interchangeable.
Cluster options are:
Speedo, Big gas gauge, idiot lights
Speedo, Big gas gauge, oil pressure gauge, temp gauge, volt gauge (rare)
Speedo, Tach, little gas gauge, oil pressure gauge, temp gauge, volt gauge
Earlier MJ automatics will have a P RND321 in the cluster for the column shifter. None of these came from factory with full gauges.
I'm not 100% on year ranges, but this is what I believe they are:
84-86
86-mid 87
mid 87-90
91-96
The second and third ones should be interchangeable if you retain your current speedometer.
Keep in mind you'll also need an oil pressure sender, to replace the switch next to the distributor, and a temp sender to replace the switch in the back of the head. The tach may also need to be adjusted, depending on whether or not your truck and the donor had the same number of cylinders.
