Quick question on firewall thickness

What Gauge is the metal used on the firewall. I've been searching, but coming up empty handed. Is 16 Gauge too thick to use? I am planning to smooth the ac and heater box holes and shave down the wire gutter. Thanks all

I’d use 18ga, that’s what the body panels are.

Thanks for the quick response. Unfortunately, no one locally stocks 18ga. Looks like I'll need to order a couple sheets online.
