I have a 1969 corvette 427 and I am looking for the part number for the right side valve cover grommet. The grommet is for the tube that runs up to the air cleaner base. I order one for the right side and it was for the left side PCV grommet instead. Thanks for any info
My 72 uses 3989346 but it looks like it's just an updated number for the same grommet.
Generic non-vette specific part so should be available in lots of places

Here is the list of the grommets from the parts and illustration catalog.
Looking at your tape measure I'm guessing 65-71 GM #3894337 but you would be a better judge of that.
The 3894337 is a superseded part number and judging by what I found on e-bay the opening would need to trimmed.
I did find the original GM #3989346 if you want to look that number up on e-bay...
