Thanks for posting. If the ochre is correct, it suggests the switch to an internal dash speaker like a pickup happened between 156067 and 165204 at Flint.

The double wall top was dropped for a single wall top. Later in the model year, the traditional K5 dash was phased out for the pickup style with a speaker grill. Interesting.
