this is kind of offtopic, but since the group is generally a good resource, here goes:
a rodeo (-97) has a bypass system installed which uses small grommets (small, fingernail sized rubber gaskets with a hole in the middle)
the company which made the original bypass system is no longer in business and can not be contacted.
is there any kind of general resource for something like this? who might be a manufacturer of rubber grommets? the only requirement is that they must be able to handle very high temperature and of the obvious, a specific size.
