Thank you good info guys.

"The other location I have seen the a/g hoses pass through the firewall for 70 Plymouth is the dimple about 1' to the right of the one shown"
is it the same height or down less visible like behind the valve cover or engine?

Can anyone answer the question if drilled or drilled and does anyone know of a legit AG car with a hole in one of these 2 locations?

Careful, your character's showing!
