I don't know of a company that makes replacement gauges for 36, but I have several or more stashed away and will look for them and let you know what I have. There are differences between standard and deluxe. What is your car? terry
There are 3 different speedometers.Delco,SW and Waltham .I don' think the faces interchange if that also needs replacing. The dual gauge faces on either side of the speedo will interchange if that is what you have.2 different colors in 36.
Can you post a close up picture of what you currently have? As said, there are two colors, which look very similar. One is more on the gray side while the other is more on the brown side. The gauges and speedometer should all be the same color.
