What color goes where?

Almost everything is body color except the trunk interior and underside of the trunk lid which is satin black. The bolt in panels at the back of the front wheel openings are also satin black, as are the two hood support braces under the insulation pad. Many of the lower areas like the rocker panels, floors, and wheel arches should first be treated with a rock resistant coating before painting. - Michael Trei

The 164(Gray) was introduced in 1969. I have never seen an original car pre 1969 with the trunk color 164 (gray). The trunk shall be satin black for cars pre 1969. Even after 1969 there were original cars with satin black trunk. I can't tell the exact vin when that changed. - Stefan Arnesson
