New here.  Looking for some gauges for our restoration on or 1938 D2 3J.  Looking for original style and also direct me to where to get rebuild parts.  Thank You

Finding original gauges may be a challenge, however I think ACMOC May have new faces kits, if your existing gauges are still functional.

If they are not working, Caterpillar offers replacements for the fuel pressure, temp and oil pressure. The faces will be more like a modern gauge and they will be smaller diameter, without the large exterior flange. The gauge face however, is the same size as original. For each new style gauge, you will want to order a 5B-9683 adapter.

Best of luck on your project!

Thank you for your response. I have the original fuel pressure gauge and can get an oil pressure gauge. Where can I get the face kits?
