Temp/fuel gauges
Look for clusters 67 Thru 71.
Stay away from any that have the needles more than a couple needles widths below the lowest mark on each.
The repo temp gauge in you photo is the lowest I would use used.
I have found many that are in perfect working order for 50 to 100 for the cluster.
Look at the back nuts as well for signs of corrosion or rust.
I forgot.... The 67 speedo has the screw on speedo cable. And the 67 thru 68? Water temp the normal scale is shifted to the right.
