Is this the firewall hole where the source vacuum for climate control enters?

[Michael L.]

Guys,

I'm trying to sort out what goes where in the firewall still. I'm pretty sure this hole is where the single vacuum line for source vacuum for the climate control goes but wanted to see if anyone can confirm that. It's the correct size and location from what I can see in the AIM but it's not very clear and the TIMJG isn't helpful. Please see the attached pic. Thanks for any assistance.

I can confirm. You are correct. I just replaced that line last week, so it is fresh in my mind.

P.S. - There should be a rubber grommet in the hole... it is more visible from the inside of the car than from the under-hood side (at least on my '69).

I've looked and I can't find a replacement. I'm re-using my original.
