Chris, here is a scan from a 71 catalog of the 2 5/8 gauges. Autometer didn't have any pro comps or sport comps at this point and the logo was a little different. The Part numbers are different on the early gauges also. I may scan some more Autometer stuff in but it may be better suited for the day 2 thread instead of here. I was just stoked over the new shifter boot

. My next step is to get the new engine fine tuned, Phone calls placed to the Plowmans house are extremely informative....
I acquired a lot of Autometer stuff from Dave Miller and added to the collection over the last couple of years.
