I don't mean to disparage any of the other vendors but I've installed four of these in '67 B-bodies and the DMT one is the only one that worked (no leakage or drippage).
i was going to mention the quality of some of today's reproductions.
when i replaced the tank in my charger, i went through several of those grommets until i found one that fit correctly in the tank and fit the filler tube without leaks, or having a center hole too small that the filler tube would not even come close to being able to be installed.
i finally used a genuine mopar grommet for a 90's [?] dodge truck application, although i can't recall what model it was for. hasn't leaked a drop since it was installed a couple of years ago.
