Interesting...
I poured through my '70 dealer code book and did not come up with any option code for D-O-D-G-E lettering other than it was part of all power bulge hoods.
As for the hood front trim being painted this would have to mean that it was likely that the leading edge "bright" areas of the healight bezels had to be painted to match the hood trim otherwise it would not look right. How did your bezels look?
