The clock was included with U17. Plenty of '69s out there with added gauges and no clock.

There was a trim option for the standard interior, Z23 Special Interior Group. This included the woodgrain on the dash cluster and other trim. A Z23 car built without a radio would have the woodgrain block off plate. If no Z23 it would have the standard block off plate with the vertical ribbing. If you need the non-woodgrain plate make sure it isn't the pebble-grain plate from a later Nova. Fits but is not correct.

Camaros built without a radio have a black cardboard cover taped to the bottom of the dash speaker grille.
