This is a new reproduction manual oil gauge. This is for the MB, GPW, CJ2A, and CJ3B. It will fit the M38 and M38A1 if you are using a manual oil line and not the electrical. This requires a 2″ hole to fit. (standard gauge hole in the jeeps listed) This has a black bezel and real glass. If you want a green bezel you will have to paint it. There is no back lighting just like the originals in the MB, GPW, CJ2A, and CJ3A. This oil gauge will hook directly up to the ORIGINAL oil gauge line fitting. (metal line under dash) Plastic is not original. This is for the gauge only.
