I agree with what California98Civic said , as it was with my old explorer only one light bulb for the gas gauge and temp gauge only one light for the tach and the speedo.
Gereric LED's are the way to go I believe.
Maybe go to a junkyard and get a nice cluster with a tach if you don't already have one and solder the LED's to the points. Would be very clean and look good.
