67 GTO frame off resto help
I have a couple of quick questions about the correct color of some chassis components on my 67 GTO. I'm in the midst of a full frame off resto and am trying to restore it to near concours quality, or at least show room quality. Does anyone know what color Pontiac painted the rear diffs on the GTO in 67? I'm not sure if it was black or cast iron. Also, what color did they paint the coil springs and steering components (center link, tie rods, swaybars, etc)? Any help would be appreciated.
