Installed my restored rally gauges this weekend. They work perfectly! Steady as a rock, no bouncing around. Pete had shared pics of my temp gauge, with two senders I sent with the gauges, showing the temp at the first and middle hash marks. The first Mark is 180 degrees. Middle is 208 with the new sender, 210 with the old sender. When my needle hit the first mark, coolant started flowing! I'm a happy camper.
