Note!
Warming the guide frame will help to expand it slightly, making it easier to fit.
To fit you may need glue (NOT SUPPLIED)
How to measure
The 1st measurement is the outside diameter (OD) of the ceramic ring. (The inside diameter of your existing rod guide frame)
The 2nd measurement is the inside diameter (ID) of the ceramic ring. (The hole that the line passes through)
