74Z at local car show, no stripe

First place to look would be the vin number and check the engine block serial number. Can't speak for sure about the rear emblem. I have a 72 but my emblem is a decal on the center of the rear spoiler.

In 74 the rear sticker was a dealer installed over the counter. I’ve talked to one gentleman who got a LT so there was no banner over the back unless special ordered. His dealer stuck one right under the Camaro emblem on the tail panel. I have a photo in my pc.
