Other than the differences between Automatic and Manual. Are there any differences in the Instrument Clusters from the different years and models?

93 had more hash marks than the 94..

 

R1/R2 doesn't have a cruise control 'engaged' light. <edit> confirmed that fact with the parts list.

 

In short, nothing major. You can live without a cruise control light, and the hash marks on the tach are completely a matter of taste, but you'll get used to them.

The clusters are all interchangeable from all 93-95 models.
