I found one down by the drivers' side pedals (if I remember correctly), under the carpet..there was just some plug there, pulled it out, and voila!

Just drill one like everyone else.

Make sure you use a rubber grommet or some silicon to seal the hole one the wire is through...

There's absolutely NO clutch hole on an automatic. If yours had it, your car had a 5 speed at one time. How do I know this? Because I converted my auto to a 5-speed, and trust me when I say that having that hole would have shaved at least 5 days off my project. The hole I cut looked like something a drunken blind man could have made.

But anyway...

On Camaros, because the battery is already on the passenger side, going through the firewall is by far the cleanest and easiest way to go, although on non air conditioned cars, right under the heater box is pretty easy too.

On firebirds, you're wasting cable by going over to the passenger side, so you should just stay on the driver's side. With an automatic, the area where the clutch master cylinder would reside is a great spot, but like I mentioned above, the hole isn't already there. On 5-speed cars, you can go right under the clutch master cylinder, but BE CAREFUL!! I drilled right into my damned master cylinder. The master cylinder points down at an angle, so even though you think you're safe, you're not. Changing the master cylinder without pulling off the brake master cylinder and booster is a huge pain in the *** until you get the hang of it.

I know I had a hole (plugged, though), where it would appear a clutch petal would fit perfectly....is it different from Firebirds to Camaros at all...? I can take a picture if you'd like, and I'm positive my car has never had a 5 spd.....

Well, I had a hole by the brake booster, that was capped up with a plug, about a 1/2 inch big, I guess? I knocked the plug out with a hammer and punch, and ran my gauge wires thru it. I wonder if the pre-drilled plug "disappeared" (or appeared!) after a certain year of car? I always thought that hole was for a cruise control cable or something, never thought it was a clutch hole.

Maybe if I remember, I'll take a pic of it tonight.

the clutch master cylinder hole is about 1.5" by 2" oval shaped. Your hole must be for something else.

The 5-speed cars also have a reinforcing plate around the hole that the autos don't have.

Another idea - use the hole where the hood latch cable goes thru the firewall. Just under the relay bank by the master cylinder. If you pull the grommet out, there is plenty of room around the cable. Either modify the grommet, or just leave it open. It's not that much of a hole.
