It's been a WHILE since I've had cordobas. I've had all that apart when I did. I have a 78 fury now that has the same dash and id like to add the clock as my cordobas had.
IF I REMEMBER RIGHT I think I took a screwdriver in that metal trim piece and it popped out easily, and the clock attached with 2-3 , typical "dash screws" from the front behind that metal trim.
