From my research, I think in part, due to Lloyds amazing restoration research and work, the Z28 302 fuel line clips have been covered but, for the L48 with Rochester carb duel line, frame rail clips, Im unsure about the colors. Two of these clips can be seen underhood. I've seen posts refering to green , black and even cad plating. I've not seen any original underhood photos and, even if the're were, the lighting would need to be perfect to tell. Does anyone know the proper colors for these 2 underhood clips?
