Pretty simple really, I used a brand new sharp utility knife blade and carefully removed the material at roughly a 45-degree angle to the surface of the bushing. Because the plastic material is so hard, it worked pretty well. You are just trying to make a slight relief so that it doesn't bind against the base of the pin on the selector rod. Also because the plastic is so hard, and the tolerance to the pin is good (very little play in the bushing when slid onto the pin), it definitely could bind at the base of the pin and make it feel really tight. I think that it would take quite a while for this to wear enough to loosen up, and it might not really wear or change much because the plastic is so hard.
