There are no known anomalies for '69 Norwood striping. The top of the cowl on white stripe cars was sloppy on early builds, transitioning to a much cleaner appearance early in '69. They had to relocate the Camaro badge on the trunk lid for cars built with D80; the pre-punched holes under the spoiler were taped over. Hole punching was changed as of April.
Some early production Van Nuys builds had the '68 rear stripe layout; some non-vinyl top VN cars had the shorter VT rear stripes.
Make certain your painter knows what he is doing. Common to see incorrect rear striping, usually extending onto the lip of the trunk lid on cars built with D80. Rear spoiler was mounted prior to striping; stripes terminate at the bottom of the spoiler.
