JermBizzle:
Would you by chance happen to know if they make a cluster for the 88-91 civic that has a tach on it AND is in MPH rather than KPH only?
Any usdm Si cluster will have a tach with the mph speedo. There's also a rare edm cluster that has the 9.5 tach with the mph speedo that goes to 130 or 140 I think. Good luck finding that one though.
