No need to swap whole cluster. Just swap speedometer and tach. Tach is just a pop up thing. Speedo is litte bit complex. But still really simple to do. If you don´t have tach originally. No need to bother installing stock GT. Just get autogage tach. Still if you want to put stock gt tach in you´ll need to run some cables from EDIS module to the dash. Still simple to do.
