Just got my new wiper assembly, purchased off Ebay for $13.03 (free shipping). The listing was slightly vague so I was concerned that it might just be for the rubber insert. I'd abandoned the stock part and added a hook to the arm so I could simply attach an "off the shelf" 12 inch wiper. Found it in a misc box of wiper parts at NAPA...good score. I'll add a picture of that transition piece in case one of you guys want it. Wouldn't mind finding a new "nub" at some point and maybe some fresh attachment screws.
