welcome to the garage Roller, and welcome to one of the more frustrating areas to deal with on the Task Force series

you need to remove the whole gauge cluster from the dash [that's what those 3 screws are for] and on the back you'll find a whole bunch more fasteners that hold all the bits together .... go slow and you'll get it all figured out, usually the top of the cluster needs to come out first [tilt forward] and it may take a bit of prying to get it
