If you want a drop-in kit, you'll need item HYB-CMC-01-20, https://www.hybrid-racing.com/products/h.... This part number does not require you to change any internals.

If you have kit HYB-CMC-01-02, you will need to follow the instructions above, which show you needing to remove the clevis and rod.

Are there any pictures of how the clutch line attaches to the slave cylinder?
