I got a Model F XT in its original box recently on a pretty good deal. But I noticed that the spring under the 8 key on the numpad is bent. It registers as being pressed continuously or sometimes not at all. The switch doesn't click, feels almost linear. My plan was to just switch the spring with a less consequential key, but I can't seem to remove the thing. The chopstick method doesnt seem to work, it won't grip the spring since it wont go in far enough. Any ideas on how to fix it bar disassembling the whole thing? If thats what it takes I'll do it. Also, any idea on where to get a replacement? Thanks.
