Special L78 Nova Code Under the Heater Core Cover?

[WILMASBOYL78]

I will look for the original pics. As for paint codes on the firewall...it is my understanding those codes were written on the bare firewall prior to the body color being applied. The firewall was painted after the body...so it would make sense that you would have to sand off the black paint to see the original markings. I checked with Wayne and the markings on our car were on top of the firewall paint. Perhaps others have different ideas....
