The Chevrolet "Advance Design" gauge cluster looks much the same between 1947 and 1953, however a few differences do exist. For the perfectionist, these changes are important.
In 1947-1948 the gauge needles are short (5/8 inches) and painted red. Between 1949-1953 the needles become longer (3/4 inches) and are white to match the change in the new speedometer needle.
The other variable is the temperature gauge. Though not calibrated different, its numbering changes from a maximum of 212 degrees to 220 degrees in 1953. With anti freeze and now a pressure radiator cap, fluid could reach a higher boiling point than 212 degrees.
