It looks to be correct to me, the only differnce between the 69 bird radio and the 68-72 GTO body style radios were the push buttons, the bird radio had longer buttons. The radio you show appears to have the longer buttons, however they could be pulled out to mimick the longer buttons. I have a 68-72 GTO radio in mine with the buttons pulled out and it looks fine to me.
Also check this site below, it was posted awhile back.
