did you think to use tape? maybe some good 200mph tape in your favorite color would have done the job, or even better and grommet, these are used mostly in the aircraft industry to prevent wires etc.. from rubbing and such....thanx for this though...now when i put mine on this week i will make sure to mask the hole so i don't get any rubbing or extra noise...watch that area for rubbing it could cause rust if it rubs hard and long enough...just my 2cents..hope this helps out...
