Hi Paul_J, The smaller holes for the gauges are slightly bigger than the usual gauges so it's tough to find single gauges of any brand to fit. I collected used '36 gauges and used the face plates and the housings. My donor truck is an '87 Ranger so I robbed the round gauges out of it and they fit right into the round housing holes for the two outside gauges.[You'll notice in the picture that they have a black background, temp and fuel]. My gas tank is from the Ranger so it should run the gauge all right and I bought a Ranger sender for the water temp. For the two inside gauges you don't have much room so I made them both idiot lights, oil press and amps. They are hard plastic tubes that my pencil grinder burrs come in, with little red LED lights glued into the bottom. The back half of each tube is painted pewter like the gauge face plates are, for reflection. I had to do my own writing on the face plates. Good luck with whole project!
