Since you're asking for opinions... I'm usually not a fan of replacing the factory gauges with aftermarket units. I understand the practical advantages of modern gauges, but the style and typeface used on most if not all aftermarket gauge retrofit packages is unappealing to me. They usually completely clash with the styling of the rest of the car. My vote would be to keep your original non-rally gauges and install a factory style in-dash tach in the 4th pod where the clock/blank would be. Then install a nice looking set of aux gauges under the dash for water temp and oil pressure, such as the Stewart Warner Green Line series (LINK).
