firewall hole questions

[sourkraut]

I had taken a picture of these before I had tore it all aprt and can not find which file I had it in. So I have marked the holes in question because I would like to weld the ones I am not using shut to clean up a little. I had found a thread on here of a firewall with everything all ready marked but thing it was al ter model than my 67'. Any help would be great, I have added to pics because I am not the best with paint. Thanks.
