Probably a bit hard to see, but I did replace all the old gauges in the stock instrument panel with Autometers, and then added 3 additional gauges in the center panel. The ones in the stock instrument panel are Water Temp, Volts and Oil Pressure. The 3 in the center panel are Vacuum, Fuel Pressure (thru an isolater) and Trans Temp. It took a bit of Dremel work on the instrument cluster, but they are nice and snug. I also had to cut the housing to provide clearance in the back, and to have a place to tighten them down, but it works great.
