Firewall holes
Getting along with the 64 C10 project, need a map or diagram of the holes to see which ones will be needed. Some are obvious, some are not.

Re: Firewall holes
That's a really good diagram. I'd just like to add that I think the hole marked "choke cable" was only used for 6-cyl engines. Pretty sure V8's had their choke cable running through another hole in the same grommet as the oil pressure line.
Also, trucks with factory windshield washers will have an additional hole for the hoses to pass through located a few inches up above the "blower fan" wire hole. |

Re: Firewall holes
Nice to see my diagram still being of use to folks.
That was a ‘65 with the I-6. |

Re: Firewall holes
The diagram was very useful for my reconstruction.
Thank you for that

Re: Firewall holes
Nicely done.
I had design/release responsibility for the front of dash/underbody structure on the GMT800/K2 program and I didn't know what all the holes were for.
