I can't remember the size but the nut bushing thing (sorry don't really know what it's called) is just a different size and they can send it to you and it'll fit then without modifying the hole. I bought one and put on my Verdine White with no trouble whatsoever. My package has the model HE6C-1/2, 20685C but when I ordered it from Hipshot I specified Sadowsky and they sent the correct piece.Oh man, maybe they did ship the right one. View attachment 4398106
So, I need to make the hole a little larger I'm guessing as it felt like it was just a hair too small. Man that makes me nervous lol.
