Firewall Components

[Bill D]

I have my firewall all set
I have my Lucas components per original cars laid out fairly accurately

What type of fasteners were used? Sheetmetal screws? Machine screws? Something mysterious?

Thanks
Bill D.

Most of the original FIA comp cars from SA that I've seen didn't have much on the firewall. Some clamps riveted to the firewall holding pressure lines to the gauges. I don't recall even seeing a Lucas DB10 relay, though it may have been on one that I don't remember. Wire's came through the firewall with just a hole. No harness plugs as used in the standard street car.
Not much help am I!

Bill, I agree with Larry.
Here's a pic of what is probably a reasonably unadulterated Cobra, CSX2436...



The firewall is quite uncluttered.

On a standard Auotlite street car, there's a little more on the firewall. Pictured in Glens photo above is the Lucas DB10 relay next to the heater hose. Above the drivers footbox (not pictured above) is the three wiring harness plugs. They are held in place by a lip on each plug. There are four nuts visible on the firewall side, that I think hold the heater in place. I don't know off hand what sort of fastener is used to hold the wiring harness in place, I'd have to check. Of course, there's a hole for the wiper drive tube, the heater hoses and footbox vent control cables.
The FIA cars are different though and probably different from each other as far as appearance. Kind of depends on what you're trying to replicate.
