Lots of vehicles got multiple different clusters, For Chrysler cars with the
shift indicator in the cluster there were 2 versions just for the 3.0 V6,
one for the 3 speed that said PRND21 and one for the A604 4 speed that said
Different clusters with a tach for different engine redlines.
Different included gauges,
Analog and digital versions.
For example think of the different ones for the 2nd gen Caravans like mine,
there is a cluster, probably 2, w/o tach, a few with tach, and a digital
version that the Town and Country got. There are also surely different
versions for cable driven speedometer vs. electric.
As for cluster swaps it might be a simple R&R job that plugs right in, and
it might require extensive modifications. Of note is that around 92 was the
year that Chrysler switched from cable to electric speedos.
