I not thank all of you enough for your help on this one. I do have one question. I noticed the lower bracket does not include 67, was there another bracket used?
I suspect that was a Camaro only thing- note that the auction there mentions Camaros only and not Firebirds. I know the upper bracket is correct, because it looks like mine, but I suspect that the lower bracket is specific to Camaros that mounted the 8 track in the back of the console, with an armrest pad on top of them. (Firebirds always had the 8-tracks in front, under the dash. I'm afraid I can't say for certain now what a lower Firebird bracket looks like. Hope this all helps, but btw, don't thank me- I don't want to ruin my reputation of only posting bad jokes and never offering anything useful....... ;-)
