Fuel Filler Neck Grommet Replacement

I just replaced mine on my 1968 Dart and the one that came off was square on both sides, pretty sure it was the original one. Maybe thats what the ebay ad means by "correct fit"
Either way you should be good. I left my filler neck in place, took off the rubber boot in the trunk and was able to side the tank on with some vasoline on the gromment

Do I understand that you did not unscrew the filler neck from the outside of the fender? And did you replace your grommet with one like I described that was square lipped on both sides.

You got the wrong one. They didn't send you what was in the pic. I'd contact them and get the right one.

Any idea if the one they sent me is meant to work? It looks like some of the grommets that I see advertised for my car on the internet. Some are rounded like the original listing and some appear to be universal with the square edge on both sides. I sent them a message but they are yet to respond. Not sure what I am going to do yet. If I don't get the grommet swapped tomorrow then I guess it will have to wait until after Carlisle.
