What type of firewall grommet should I be looking for?
Looks like there's a couple kinds on eBay. I'm looking for the one the wiring harness for the dash goes through. I don't have the car with me to check.

Well, which grommet are you exactly looking for? If you are talking about a 1967 Cutlass, the wiring harness for the dash doesn't pass through the firewall. It runs from the fuse box to the dash, period. If you are talking about where the main harness from the fuse box passes through the firewall, there is no grommet. There is the rectangular firewall connector on the backside (ok, technically, the FRONT side) of the fuse box. There should be a foam seal around this connector. The HVAC harness does pass through a firewall grommet.

I'm replacing both the dash and rear engine harness and the A/C harness. I thought they all went through the hole the vacuum hoses for the A/C controls went through, but whichever ones I need to replace are the ones I'm referring to.
