What are these holes in the firewall for?

[67RSSS502]

I am wrapping up all my connections and fittings over the next couple of weeks and have come across 3 holes in the firewall that I am not sure what to do with. I have indicated which hole I am unsure of and have looked in my assembly manual and can't seem to find them anyplace. If anyone can identify them for me it would be great.

Thanks!

Pic one looks like the factory clutch actuator hole and the e-brake cable hole. Pic two looks like the factory accelerator pedal hole. I'm just going off of memory....which isn't that good. Do you have these items routed in the correct holes? If so, don't know what they're for.

Pic 1 is the clutch boot hole for the rod to go through and the speedo cable hole. Pic 2 looks like a hole that was put in for gauges that were an after thought but I am really not 100% sure about that one,haven't looked at a stock 69 for a long time.

Hole #1 - same as Jim said. Hole #2 - picture pretty dark but maybe for gas pedal linkage? If that's not it, it doesn't belong there

Way to dark, gas pedal linkage hole should be behind the valve cover, over farther
