Can anyone help me with finding the correct color (semi-gloss?) or color code for the black paint used for the lower body area used on 1968 Chevelle SS396's? My car is already painted black in that area, but I want to re-paint it and I want it to be the correct color. Thanks for any info.

It should be 60% gloss black. Any paint supplier can mix it in enamal.Then reduce it and add hardener...
