Great job on the firewall!
That's exactly what it is. I'm using an Ansen dual pedal setup which is designed to use the early 60's GM pickup twin (brake/clutch) master cylinder. Just need to swap the innards from one side to the other to have the brake and clutch systems on the correct side (which takes all of 5 minutes) and then everything just bolts together. Don't for the life of me understand why Chevy's pedal linkage reversed the sides but that's just the way they did it.
