Hello Dave,
From my experience, it isn't easy,but can be done,with using "patients", if you have access to a diagram, maybe on the internet or local library, it'll make it easier. Models with no visible screw heads in view, look under dash, remove those first, some of the panels could be just "clipped" in. Once you find how the panels are removed--not so bad.When you expose the cluster panel itself,there probably are several screws that will be visible.The lighted portion of the panel is a contained unit within itself, lean forward and if needed unplug any connectors,so as to allow access to bulbs.
Hope this helps
In Christ,
Walt
