Number matching questions

I got my A body from the original owner years ago with 16,439 miles on it (drove it for years after that). I never checked the numbers but it has come up with the insurance company and value after the restoration. Since it's a 1967 Dodge Dart GTS am I right that they didn't put vins on the engine, trans, etc. so I have to check date codes? Also where do I find these?

Insurance company is also saying it's not a GTS because you couldn't order that package until after 1967.

I have the build sheet for the car.

Thanks for any help on this.
