I have no idea, but I solved a similar issue with a set of Suntour Cyclone calipers that (apparently) required a slightly smaller (like Campagnolo) bolt diameter when I already had several sets of nice polish finished Kool Stop brake shoes with new dual compound pads with larger Shimano spec bolts. A chopstick wrapped with a bit of sandpaper will solve the problem if the CLB brake arm slots need to be made a bit larger to accommodate Shimano-style shoes. Then you'll have lots of options without having to go down rabbit holes looking for arcane pads to fit modern shoes.
