T-Tops on '74 Z28 Camaro?Found one with this feature.I don't believe this is an original option for this year camaro.Am I right?

Like the one on Ebay? T-tops did not show up in production till 78. There were some that were fitted by specialty shops back then. I believe they were Hurst. I would have went for the 74 Z on Ebay but the tops turned me away.
