I am needing a little help in trying to decode this tag. I am fairly certain the body color was Ivory from the factory. However, I cannot identify the other codes. Thanks in advance for any help.

 

11E built 5th week (E) of November 1967 (11)

68-4287 1968 model year, 4200 Cutlass Supreme, 87 Holiday Coupe (2dHT)

LANxxxxxx Lansing assembly plant sequential number

974 Willow Gold interior, Strato-Bucket seats

T-T Ivory upper and lower body colors. Unusual that a C/S has no vinyl top.

 

Thanks so much for your help with this one.
I agree not having the vinyl top is different. But, this particular car is pretty different all around.
Not sure how much it matters, somewhere along the line the exterior and interior colors were changed. It would, I suppose, if the car was unusually optioned.
