As far as I know the cowl tag only identifies the exterior and interior colors. The striping colors are not shown on the cowl tag at all. They might appear on the body broadcast sheet, but again as far as I know they are pretty much non-existent on Norwood cars. Your car most likely came with stripes. I've never heard of a stripe-delete Z28 from 1977-1981 models, but I guess it could have been done if a car was special-ordered for a customer that didn't want the stripes. Otherwise determining what exact stripe color combo came on your car would be next to impossible short of finding photos from the original owner.
