D96 was available on any 1968 or 1969 Camaro as a "stand alone" option (Not available in 67 as a "stand alone" option). It came standard on 1967 and 1969 Camaro's with the Z22 Rally Sport option, but for some reason, not the 1968 Rally Sport. It also came standard on the 1969 Z11 Pace Car and the 1967 and 1969 Camaro with the Z21 Style Trim option.
As for colors, the same rule applies to the D96 striping as to the rest of the striping.
