52 Merc Gas Tank

[RalphG]

I am doing a test fit of a gas tank on my 52 Mercury and can't seem to locate the rubber grommet that goes around the filler neck behind the license plate. I did a brief search at C&G Ford but could not find anything like that listed. Its years since I removed the original rusted out gas tank and the rubber grommet (if it had one) seems to have gone missing. Did they actually have one originally or am I searching for something that never existed?
