The Honda top box calls for drilling two 20mm holes in the existing rear cover (after you remove it) using a 20mm hole saw. The location and size of the holes is well marked on the bottom side of the cover. The sleeve that sits in the hole is 18mm. A 3/4" hole saw is about 19mm. Has anyone use a 3/4" hole saw or has everyone had or purchased a 20mm hole saw when doing this install? Thanks..
