Cut plug. Trim plug. Flush sand plug. Refinish.
Naaah, that's too time consuming.
Make a bigger bushing!
In this case the existing holes are just slightly too big for a satisfactory fit. I cut some aluminum tape strips the depth of the bushings and wound the strips onto the bushings to increase the diameter. In my case I cut the strips 10" long which proved to be a correct guess. Your strips may vary depending on the diameter increase you need.
