Thats interesting Badshifter, I was told by 2 former owners that my Z28 had a cross ram setup on it. I have always wondered if it came like that from the factory as I have never found the original owner to verify it. Recently I reached out to Wayne Guinn, he's pretty knowledgeable on cross rams. He had me take a picture of the my firewall that I posted on here and to the left of the hole we are questioning there is a ground strap and to the left of that there is a small impression. Original gm cross rams use a v6 pedal and it goes through where that impression by the ground strap is. He thought the hole that we are wondering about might have been used for a after market cross ram. My hole has a grommet in it.
