That you have seen others is a growing concern to us old-timers who knew what '69s were like. Today one can routinely see houndstooth seats in standard interior cars, cars with console gauges but no clock, the famous CAUTION-FAN decal, ducted hoods on everything, unpainted grille surrounds, '67-'68 N34 wheels.
Last week an acquaintance sent a link to a '68 Z/28 for sale with a ducted hood. The dealer swears it is OE.
Used to be I'd never comment on a '69 unless asked. Lately people ask, get po'd and don't believe you anyway. But to answer your question, no white stripes on a Garnet Red car unless it had a Parchment vinyl roof.
