For sale is a new Rex-A-Co water temp gauge in excellent perfect unused condition. 2 1/4 inch outside diameter that fits 2 1/8 inch standard opening in most gauge panels. Mechanical gauge that has 58 inch line with engine adapter and has a wire for the built in gauge light. I believe these gauges were offered by John Wilton about 1990, so this is a 30 year old gauge in brand new condition. John Wilton reproduced a few very high quality early Ford parts for 3 or 4 years in the early 1990's. $75 USD plus shipping.
