I've got my wiper motor out and found the problem with the wipers. I've got a couple questions and I searched and couldn't find the answer. I've ordered the ebay kit from 59imperial but I need to know if I have to remove the drivers side wiper arm to attach it to this plastic drive crank and does the arm go between the two "fingers" on the plastic drive crank (the whiteish parts in my pics.) Also how is the drive crank removed from the arm? Thanks for any help.
