My car also had a 'T' down below the trim plate, but it wasn't visible until I removed the brake booster. In addition, there is the standard 'PTB' over to the right of the trim tab which are more visible. I think we referred to the 'T' below the trim plate as the 'second T'... Is yours the same? and was it your intention to post that ALL Camaros have that second T under the trim plate?
