That's how mine are. Males up against the side windows and females toward the center of the bench. Mine are original. My grandparents bought the car new, and I am the second owner.
I would love to hear more about what you did and how you did it to get to this point. My 67 grill could use the same, and I have been pondering how to approach it.
Fury road, when I posted that link I did not look closely enough to realize that none of the TTI 360 headers is for a 1972 C body. The mistake is mine. I just muddied the water, and I apologize.
I have black TTI headers on my 440. Bought them in raw mild steel and ceramic coated them black locally. May be an option for you to get the color you want.
Also, I think TTI does make headers for the 360. Seems like they have several different ones...
