Todd: THANK YOU!!!!
It is finished. I had purchased the new shoe over a month ago, and it's benn sitting on my desk. It wasn't the least bit obvious to me how to install it, and web searches have been fruitless. In the meantime, I had forgotten that I had posted this question here.
The only thing you left out was how easy it was, and how ham-fistedness is a great asset to the operator. ;g ;f It is now very obvious to me why you super-glued the third one.
In light of Nikon's general excellence, this is a hopelessly weak link, as I already know it will break again within a year. Certainly a job for titanium, or somesuch.
You have my eternal gratitude, sir.
