Jim,
I ordered and received a complete set of fuzzies and channel replacements. You were correct in that is an all day job. I, like you, used the existing screws to replace the outer fussies but instead of wire for the inner, I drilled small holes and used very small stainless screws to hold them in place.
They are almost countersunk and did not interfere with the window travel. I had to hold the fuzzy in place with clamps in order to drill the holes accurately. The channel replacements were easy once the window is released. I just used weatherstrip glue on the back side of each an slip them into place. The short one has a small screw at the bottom to keep it firmly in place. The kit I ordered came with two strips of fuzzy for the upper horizontal and rear vertical that I just clued into place. Gregg
