Default Firewall Grommets

I'm ready to order new firewall grommets for our '77, but wanted to see if I'm forgetting anything. Most of this is missing from our car, so I don't have a good reference point. I do have an AIM, but it's not clear or doesn't show this information well.

Hood release cable grommet (found this on multiple sites)
Clutch linkage grommet (unsure of what should be in the car? Is this just a large plug with slits cut in it?)
Steering column seal (have this taken care of)
Speedometer cable grommet (found on a couple of sites, but I'm unsure of how to get it over the cable ends?)
Headlight vacuum hose grommet (should this be a 2 hole? It appears that the reverse light switch wires also run through this, but they are actually between the grommet and the firewall instead of running through the rubber grommet?)
AC wiring grommet (unsure what I need for this)
Heater / AC vacuum line grommet (this should be a 3 hole correct?)

Is there anything I'm missing from this list?

Thanks for any help!
Adam

Hey SR - Those would be on the firewall to cowl area correct?

Thanks,

That is correct. The hoses enter the cowl area through the top of the firewall through two grommets.
