This photo from the March 1969 issue of Motorcade shows the rear stripes in yet another
configuration, basically the same as the '68 Z/28.
The "low" rear stripes definitely did happen, although it probably was only at the Van Nuys
plant. I saw several examples of '69 Zs back in the '70s with this low stripe treatment, one
in my hometown which was still in the hands of the middle aged original owner. I don't
think the CRG database has enough info at this time to determine whether these low rear
stripes were only done during a short window of time or if there were other times during
the production year when this happened but it is something that is being looked at more
closely than it has been in the past.
