Most of the time those grommets are pretty used up. They are hard to find OEM if I recall. I do seem to remember someone on here who made up a replacement, but I can't remember who or when that was.
I've seen a fair number of folks on here use an RTV sealant for the grommet space with no ill effects. Needs to be oil and petroleum resistant, and applied carefully so as not to goop into the stator area. Sure, looks blah, but it will suffice.
