I noticed on my 69 that I left out one of the plugs that hold the firewall insulation on. The location is up above the brake on the firewall. I have a plug and could not get it to push through the firewall all the way to secure on the engine side of the firewall. I was trying this by myself and maybe it's a two man job. Any secrets on a way to push this through the firewall?
Thanks,
Lawrence
