yeah, the gauges are basically 1 long bar that spans the length of the 3 gauge holes.. with circular protrusions ( the gauges) its 1 big plastic piece that needs to be cut into pieces and removed.
then you can dremel away enough space to tightly fit and epoxy the new gauges to the dash itself.
look for girald_s channel in youtube ive got some crappy videos on how i did the job...
the gauge wiring is enough to power the new gauges .. its fairly straight forward once you get the courage to destroy the oem
