I know it’s not all original... but I’m curious about these housing clips on the top tube. They’re Dura-Ace and the rest of the Shimano stuff on the bike seems to be 600. Can anybody who bought one of these new comment on whether these are original? Did Shimano have different housing clips for the different groups?

(Also someone overtighetened them and crushed the housing and kinked the brake cable, which I’m glad I discovered before I took it out for a test ride with no working rear brake!)
