I THINK ALL THE NUMBERS ARE RIGHT.

Here you go:
Decode for body number: 110931
04C = Built the Third week of April.
67-12437 = Standard Interior Coupe.
NOR = Built in Norwood Ohio.
709 = Standard Gold Bucket Seats.
Z = (A50) Strato Bucket Seats.
G = Interior paint is Gold
Options:
2G = (D55) Console front compartment
3S = (Z23) Interior Decor group
3K = (Z21) Deluxe exterior trim

You missed the paint code and I guess at the 35X to be 3SK. If you post the vin# I can make tell you if it lines up with the cowl tag.
