hey for all u guys that r saying ur hole is super tight that is fine but u do want a little gap because a friend of mine drilled out his holes and were super stight and from all the vibration just from riding it actually made a couple little cracks around where his slider is so u do actually want a very small gap prolly like 1/16th or just my 2 pennys though

 

Not an issue if they vibrate at the same frequency where they contact.
