This tool worked perfectly to remove the wiper arms from a 1966 Chrysler. I was able to hold the wiper arm and tool in one hand, and with the other hand use a small slot screwdriver to pull back the tab which holds the wiper arm onto the pivot. Then I wiggled the wiper arm gently to walk it up the pivot splines until it came off. No risk of damage to the cowl paintwork, and the tool did not flex or bend. I have no reason to doubt that this tool will simplify reinstalling the wiper arms as well.
