67 Dart fuel filler tube gasket/ tank?

I ordered mine from YearOne. When I spoke to them on the phone they said they didn't have one for my 67 Dart. Only year they don't make one for. But they said the '66 gasket would work great but just be a little snug putting the tube back in. I put white silicone grease ( vaseline would work also ) on the gasket and tube went in with no problem and seals great.
