70 Nova firewall help
 

Hey guys, I'm looking for some help to identify unnecessary holes in my firewall before painting.
The only ones I know for certain are #4 &#6 for the wiring gutter
I think #10 is for a speedo cable clip but this hole was filled solid with tar/butyl sealer.


When I pulled this apart the wiring harness was "P" clamped to the firewall and unfortunately I did not mark the holes then.


1970 L78 4Speed, no gauges

Do you have an Assembly Manual? I have one here for a 69 Camaro. I would think Nova AIM s are the same or real close. Look on UPC 0 Sheet A9. That has the cowl and dash panel piercings.

I'll look for it there. Thanks
Any other input appreciated.
