Grommet help

[Pontiac787]

I’m looking for a grommet with a 1” OD and 3/4” ID to fit a K&N breather in some old Edelbrock cast aluminum valve covers. The port in the valve covers are 1” across by about 3/8” deep. Neither Edelbrock or K&N could offer any suggestions. I got one from Scott Drake for a ‘67 Mustang with the correct OD/ID but the gap is not wide enough. I trimmed the bottom lip off to fit but the center gap section is rounded so it’s not an ideal fit.  Anyone know of a compatible grommet?

Thanks. That one is 1 1/4” OD. I found that the R9760 has the right OD/ID so I’ll see how that one fits.
