For sale is a four (4) gauge pod designed to hold 52mm gauges. Despite being designed for a Right Hand Drive Legacy, the pod seems to be pretty symmetrical on either side so it should fit Left Hand Drive just as good, or with slight modification (sanding) of the contact area.  This product is made from fiberglass.  There may be some slight imperfections due to the nature of fiberglass manufacturing.  Having this painted and installed by an automotive professional can ensure close to 100% fitment.  Item is painted with automotive quality paint but may not match the exact color and/or texture of your dashboard.  Installation is extremely simple:

1) Remove upper center dash console just above radio.  Simply snaps out with a sturdy pull.

2) Place pod on the leading edge of the dashboard and clip the brackets under the dashboard leading edge.

3) Snap the upper center dash console back into place.

Installation of the gauges, and wiring them up should be performed by a professional, or someone with automotive experience.
Of course, I must state that only the pod is being offered for sale, gauges are not included.
