Glad to help! I think using markers like sticky notes is a good idea. I noticed that the first time I reinstalled the driver's wiper, it looked to be in the proper position, but when I ran the wipers, the arm settled still much too high on the windshield when I cut them off. I had to reposition it by adjusting that damnable pressure nut two more times to get it about right. I don't think there is any other way than trial and error to get it just right, though. Mine still sits just about a 1/2 inch higher than it did previously, but I haven't had the energy to mess with it again yet!
