Default 1970 GTO firewall question

Anyone out there have a stock GTO that can post or send me some pictures of their firewall? I’m installing all the hoses for the windshield washer, battery cables, heater hoses etc., the restoration guide I’m using isn’t very clear and I need to know how the factory installed them.

I also need some good pictures of the radiator saddle brackets. I went with a aftermarket core support and it has multiple holes..

Thanks

The 2 hoses for washers go right thru firewall at the holes seen right adjacent to motor assembly

Can you send me a picture of how the hose that comes from the washer bottle runs along the firewall?

For a 70 without A/C, The washer hose is held by a thin plastic clip that presses over the top drivers side heater box stud. It is then routed on the top of the box to the top of the inner fender. The bottom drivers side metal clip holds the blower motor wire.

You're welcome. Not sure if you have an assembly manual, but this is also called out on page 63 for the 70 model. It shows the hose coming off the pump and going under the voltage regulator (for a V8 without AC), to the top heater box plastic clip on the stud. On mine, it sits on the top of the voltage regulator, and I think it does this because of the under hood lamp switch. It also has no clips holding it to the firewall, also because of no AC, and with the under hood lamp.

I do have an assembly manual but the pages have been copied so many times they are basically unreadable and my restoration guide did do a great job of showing how it ran.
