Original Corvette wiper arms are pressed on to a shaft, often referred to as a transmission that projects through the cowl of any 1956-1982 Corvette. The fit is very tight and over time the wiper arms can really become "stuck" to these transmissions. Removal is not difficult, if you have the correct tool. Many Corvette owners have found themselves on the short end of a nasty paint scratch while trying to remove the arms from the transmission with a common screwdriver. The process can be done, but is not worth the risk just because you want to save a few dollars by not purchasing a wiper arm removal tool. With this tool your wiper arm removal will be quick and easy without risking damage to your Corvette. The tool simply hooks on to the bottom of the wiper arm elbow, grab in one hand the wiper arm and tool handle, squeeze together and pull straight up. The tool creates the correct alignment of the elbow in order to bypass an inner spring clip. Once correct alignment is received, the arm pulls off with ease.
