it will be some time before I get to that, right now I have just purchased a complete dash minus all of the gauges, so I have the cluster housing, lens, bezel, basically I was going to purchase the gauges and figure it from there, big gauge will be a speedo with smaller Tacho with in it, smaller ones will be gas, oil, water and volts. What is in my mind is turn up some thin wall tubing with a mounting flange inside and a flange extermally to enable the tube to be screwed to the cluster housing, then cut the front of the tube to match the contour of the lens similar to the factory gauges. the cluster housing will more than likely have to have large holes cut through it for the back of the gauges etc but I have nothing hard and fast until I get the gauges, big task but I think well worth it, it will look factory until you look hard, much nicer than an aftermarket flat facia etc.
