Datsun Roadster Forum-311s.org

I am considering replacing my origianl factory gauges with Autometer gauges. In the description on this site (see electrical at 311s.org) someone wrote 2 3/8" gauges fit. Autometer only uses 2 1/16" or 2 5/8 " now. I found that most of the gauges at 2 1/16" can be used if you use a o-ring. However, for the clock, the hole opening in a 66 is 2.363". My question is has anyone adapted or changed the clock out using an autometer clock? If so, what did you do?

Also, for the Tach or Speedo, the gauge size is 4.551". Most Tachs require a 4.625" hole. Appears that you would have to file down 0.074 ". Has anyone tried this? Any experiences would be helpful.

One last question? If you were to switch to a autometer fuel gauge? The site specified "Fuel gauge 2-3/8"-used Ford unit as it has correct ohms and works well-not 100% below a 1/2 tank". Since the models for autometer gauges have propably changed, can anyone list the Ohms required or a part number.

As Always,

Thanks in advance.

Thanks

Ivin,

I would be that "someone" you are refering to. I am not sure where I came up with the 2-3/8" gauges as they are in fact 2-5/8". I will fix that straight away. I am always transposing numbers. Sorry for the confusion.

I used the gauges in a custom carbon fiber dash face that I had to bore new holes into so I am not much help as to your o-ring question.

I believe I used the fuel gauge with a Fuel Level (73 ohm empty/ 8-12 ohm full) This application is for most Fords before 1989 & Chrysler vehicles. If you want to be 100% positive check the roadster sender by measuring resistance (ohms) using an ohmmeter with tank empty and full. I used the Sport-Comp gauges. The fuel gauge PN for a 2-1/16" is 3315 and 3515 for a 2-5/8".

Good luck.
