Correct AC grommet

[PbFut]

On my 72, there is a odd sized grommet hole for the ac cable in the firewall above the evaporator box. I think it is 7/8". It is a single hole grommet with only the control cable passing through. The AC vacuum and wires pass through a hole at the tunnel. The firewall hole for this cable grommet is larger than the 3/4" holes used for single wire pass like the tach and aux battery. But it is smaller than the holes used for oil pressure or windshield washer tube's. Does anyone know a source for this odd sized grommet?

Believe this is what you are looking for https://www.classicheartbeat.com/pro...cable-grommet/ All the other firewall grommets are available there as well. Wes is great to deal with. His website actually has a search function and he has a phone as well.

That is interesting. I also could not find that grommet, so it's good to know it's available for next time. To contribute to the bubble gum and bailing wire repair category I found a rubber washer at the hardware store and superglued it to metal surrounding the hole.

Thank you Richard. Shape seems correct as well. I'll give it a try.
