The car is a 1969 Barracuda. I am missing the plastic bushing/cam that goes between the wiper motor crank arm pin and the long link to the drivers side wiper shaft. Y1 shows one that is good for all A bodies but Classic Industries shows two models: one for two speed wipers and a different one for variable speed motors. Both of the CI models are very pricy. Are there really two different types? Anybody know where I can get one for less than $10?
