3-speed shift lever grommet available?

I have been looking around for replacement shift lever grommet. I found a discussion talking about what the factory part numbers are for the grommets. Shift lever grommet part number 1941699 updates to 3467791, current part. Can someone point me in the direction to locate this part? The places I have check are out of stock. Specifically looking for the 1963 manual transmission grommet.

Thanks!
