Answer
Abir,

I have no idea what the exact size of the gauges you have.  If you are looking at changing yours out to the aftermarket variety you will have to fabricate a panel since the instrument cluster is really not individual gauges.  I have seen it done both ways.  The first is to remove the cluster and take out the circuit board with the gauges and then install each individual gauge after cutting access in the back panel (circuit board removed) and then checking each wire to get it hooked up correctly.  Some, like the speedometer will have a cable so make sure you get the correct ratio or the dpeedometer will be off.  Other gauges like the oil pressure usually use a pipe and that has to be connected to the engine since it is not electronic.  Unless this is a show car or you specifically have something in mind for it the cost for conversion and time to do it is prohibitive.  The other way to install individual gauges it to fabricate a panel behind the instrument cover or over it and cut holes and install the gauges to that panel.  This looks most professional and it is just a matter of using the template with the gauges and arranging them the way you would like them to be displayed.
