How to Change Gauges in Panels...???

Can anyone tell me how to change or add different gauges to a panel. I have a wonderful pane l /w an even better overhead, however the plane is old it's a fokker 28 from project fokker. I love this plane, I just wish it had some up to date gauges, so I have come to the conclusion that i will have to learn how to change the panel to my liking. Any advice would be greatly appreciated.
Thanks in Advance!!!
