It only takes an air gap of 1/ 1000th of an inch to allow for free movement and not bind. You can’t hardly feel or see that small of a gap, you would need a micrometer to measure that close of tolerance. I could be mistaken but I’m sure that bushing was sized to allow for the air gap and no need for washers. And a bigger gap just allows for larger amount of contaminants to get in.
