OK, on the map pocket on the door panels, a 67 has like a "Sun Burst" (as I like to call it) design where a 68 has the design of a Cougar. On the front buckets, on the side of the back part, the 67 doesn't have the seat back release and the 68 does. On the overhead console the light bar on a 67 doesn't have the woodgrain applique and the 68 does. John
I believe there were different window cranks in the '67 vs '68, the rear view mirror on the windsheild is different too between the 2 years. I think the handles for the vent windows may also have been different.
