Firewall pad installation???

[HuggerSS]

When installing the firewall pad, did the factory have a punched out piece of the pad around the steering column firewall seal or was the steering column seal bolted to the firewall behind the pad. I see some of the reproduction firewall pads have a perforated triangle around the steering shaft hole and I see some without it. I have not found a unmolsted car to verify this on. Any insight would be greatly appreciated.
