In 68, the parking lights went out when the headlights came on. In 69 they stayed on.

Yup, thats another one of those 1 year only differences. 68 was the first year for the lighting group that included fender mounted lights. With that option they left the bulbs out of the direction indicaters in the instrument panel.
