As I'm moving thru my body work, I noticed that my original replacement fire wall is missing the tach and headlight vacuum holes for my charger. I must have not transferred those when I installed the replacement fire wall and don't have the old one. Can someone please let me know what the hole size is for these two holes? Reference photo shows what I'm looking for. The dimples in the firewall show me where they go, I just need to know the hole sizes. Thanks in advance.
