Thanks, looks like that thread you mention depicts the eared clamps, and the tools to use those. note the part of the clamp that is lifted up, and squeezed. I imagine thats the Ear that is referred to
The boot kit for the KUN26 that you might buy today (and my current CV boots, for that matter) use the eared style for the small clamp and the earless for the large clamp. earless seems to need a tool with a much narrower head to fit into the little hooks that let you pull it tight enough to latch
edit: toyota inner boot kit comes with two different clamp styles lol, different tools needed for each
