Thanks! I did manage to find that one once I looked up the plastic pin part number. Does no one make the metal version? Any idea why they were different to begin with? The other thing I'm trying to figure out is the felt guide. I don't seem to have that on my window. I have a plastic/mylar/something kind of "wrapper" on the front edge of the window and the metal guide blocks, so wasn't sure if this was just another 67 only kind of thing or if my wrapper stuff used to be something else in the past and that's just all that's left of it.
