dart filler neck gromet

For the grommet, if it's a 68-74 Dart, the Chrysler part number is 3404182, and it costs about $9 from the dealer. If it's a different year, I'm not sure of the number, but it's worth a call to the dealership to see what they can find for you. I see some people trying to get up to $35 for the grommet online, when the dealership still sells it for way less.
