Just to add to that. If you e-mail biketoolsetc. directly, they're pretty responsive about tailoring an order for you. I once asked if they had a replacement pin for a Lifu chain tool, and someone there wrote an e-mail back offering to dismantle another chain tool to sell me the piece. They can, however, take a few days to respond. It's possible that "they" is no more than a person or two, not sure.
Personally, I could use a set of axle spacers in various sizes, too.
