I'll see what I can find. I have boxes and boxes of keyboards to my wife's dismay. There's nothing special, just keys in a white, cloth bag. I used them to make a checkerboard-style keyboard.
Oh, and here's the weird part. There was a Dvorak kit and a regular keycaps kit. I cannot tell the difference between the two items, but I didn't check hard enough. I think the regular kit has number and special keys like Enter but I honestly don't recall being able to pry those keys off of a real HHKB Lite 2 or HHKB.
