Step 3: Remove the original lateral indicators
The original lateral indicators are simply metal dowels that are held in place by rubber o-rings that allow some resistance and hold the indicators firmly. This system is functional but imprecise and frustrating, since when you are trying to move them a tiny distance to just barely touch the rim you end up either pushing too far or not moving them all!
To remove them, simply grab ahold of the plastic tips with pliers and pull them off, then pull the indicators out the other end. You may find that another set of pliers to grasp the other end is helpful if you have them available, but they should not be necessary.
