Original Gauge Size

[Bill D]

I'm having a debate on another forum about the size of the original speedo and tachs on original cars. I contend they were 4" but two others are adamant that the S/C cars came with 5" gauges. Is there anyone here that can help sort this out?

Thanks

You're almost right. They are 100 mm (3.937"). Check out the Nisonger Site that advertises on here. http://www.nisonger.com/cobra-oem-gauges.htm
