For now I am reusing the original grommet I found. There has been a cotton rag stuffed in it for the past 19 years. It was always hidden under the firewall insulation on the inside of the cab like in your picture, but I noticed it from time to time from the engine bay. Can't explane why I never bothered to investigate. I have that it has to be fixed now syndrome and never did anything on it till now. Good Luck on your search. I would love to see a follow up picture of what you end op doing.
