1963-1966 - Late Chrome Windshield Wiper Arms. The NCRS accurate windshield wiper arms are made with the adjustable internal mechanism that allows the wiper arm angle to be adjusted as per the originals. This adjustment is done with a screw on the side of the wiper arm body.
1966 Early and Late Chrome and Brushed Windshield Wiper Arms:
1966 Corvettes are documented with both Chrome Finish and Brushed (satellite) Finish Windshield Wiper Arms. It appears that the Chrome Finish was used on only the first 4,000 to 6,000 Corvettes in 1966. In the case of the wiper blade arm, 1966 Corvette with a VIN Number of 6,000 and under would be accurate to use Chrome Windshield Wiper Blade Arms.
