Very early, Oct Nov 68 69 Z-28's had the narrow 68 style spoiler and in some cases, according to Jerry McNeish's "Definitve 69 Z-28 Book" some had narrow stripes also. Mine came with the narrow 68 spoiler. chambered exaust, no cowl hood (Larry Shinoda was designing it still). Course I added it myself cause it is so wicked looking. Mine doesn't even have X33 on the tag because its a 4th week November car, but the "X33" was marked on the back seat bulkhead, right motor, etc.
