Total and absolute success. Finally. I filed off half the keyway and put the drivers arm back on. You can then move the drivers arm downward about 1 or 2 splines more. It sits perfectly on the stainless and works excellent now. When you put the wipers back on the stub shafts, position each wiper about 3/8 inch above the stainless stop. When the wipers run and stop, they will be a bit farther away than that, but hides nicely.
One thing to look for that may cause this problem. When I first looked at mine, I could see the drivers wiper blade (rubber part) was hooking on the top edge of the stainless trim piece preventing it from going lower. The stainless trim had lifted off the window glass a bit allowing the wiper ruber to hook on it. When I removed the stainless, I found dirt and evergreen needles under it, causing it to build up. I suspect that once the wiper rubber hooks up on the stainless and wont close down farther, it causes unnecessary wear on the mechanisms which result in too much slack in all the parts to close properly. However the modification I did fixes that. Try yours and tell me how it goes, to finish off this post.
