I'm wondering where folks are getting some of the really funky grommets I'm seeing on a lot of seats these days. Some are very large and look to be aluminum, like the GT40 seats used. Others have mesh inside of them and there are some other cool ones I've seen too. Anybody out there care to share where I might find some of these cool things? I assume most of them are set like regular grommets, no? Any info greatly appreciated!
