firewall grommet

[Lynn]

OK, had to crop this from another photo. The large square hole with the radiused corners is for the fuse block. The round hole above the fuseblock hole is for the ducted hood options (.75 inch per the AIM, page A5 of ZL2). The hole below is for the brown tach wire. This is one of the ways you can usually tell if a car came from the factory with a tach. No hole, no tach.

I think I posted on another forum that the AIM states 17/64. My mistake. It is 17/32, or just over 1/2 inch, which is consistent with my car.

My guess is that my original grommet is in a bag or box somewhere. I can put the car together without it, as it isn't hard to install after the fact from inside. The aim says the grommet is part of the harness assy. There were three harness assemblies, one for no console, one with console and stick shift, and one with console and automatic trans.

So, where can I get the grommet???
