72 firewall metal thickness

Hi guys, I need to make a small patch in the firewall of my 72 Satellite. What gauge sheet metal do I need, 20-gauge? Thanks...

I used 18ga for mine as I couldn't find 19ga like the original. 20ga is probably fine.

Ok, thanks man. That's what I needed, the OE spec. I will probably pick up some 18ga. All I have laying around is 22 anyways and I don't want to go that thin.
