Anyone sell the rubber pass thru grommet that goes between the firewall and the end of the metal throttle cable housing? It mounts to the gas pedal to firewall bracket and the throttle cable passes thru it.

Last one of those I replaced was a long time ago, should be available.
Don't know if they're all the same, which car ?
Can't recall where I found one, could even have been from "Pick-Apart".
If you or someone has a photo of what you want, I may have one in the stash I can send you.
Or I can look at my '68 B & '70 A cars, if that's what you need.

I have a 68 and a 70 and can take pics....

It's for a 70 a-body, but they should all be the same. I swear that I ran across some website that had them, but can't find them now. All the used ones in the yards around here are fossilized.

Throttle Cable grommet and plug
Is this it?

Looks like that could be it. The one I have the rubber edges are 90 degrees. I guess I could buy it for that price and find out.

The original had sharper corners but, dimensionally, it's probably a common grommet size.
