the next time someone is out working on their truck, and you have a dial caliper in hand and one of the gauges (speedometer or combination gauge cluster) is out, would you please let me know what the diameter is of the gauge opening.

I'm going to be installing an Auto-Meter 5" speedometer and tachometer soon but need to find out the diameter of the gauge opening as I need to have some rings cut out as the stock gauges are slightly bigger than the Auto-meter gauges.

Thanks!!!

The hole for my speedo is exactly 5". My '50 1/2ton I just bought is missing the speedo so this was easy.

thanks for the measurement

I dug around in my garage and found my dial caliper, the opening is just about 5 3/16".
