Not sure if those are for HG or not, but they may work if the slots fit the holes in the frame. I dug in my tool box and found these. They are slightly different for different chain rings. My 1997, 1999, and 2001 frames have threaded holes in the chainstay yolk for the anti-chain suck plates. They may be on different years, but that’s all the years I have. I thought about putting them on but haven’t had an issue with chain suck.
