Alright to answer your question. Yes the CRX SI guage cluster will work but you may need to re-wire your cluster wiring. Plug it up and play, also it has to be the same "year range" 88-89 and 90-91 have different styling and different wiring pinouts. Figure out which cluster you want to put in and let me know and we can go from there.

 

thanks for all the help.. I appreciate it
