It may actually be a 68. Back then, many states titled cars according to year of sale, as opposed to year of manufacture. 69s were not officially sold here, only in Canada and, of course, Europe, so it could have been a private import---such things were not difficult then. You should be able to tell if it's a US model by presence or absence of such things as side marker lights and labeling, in English, of all the controls on the dash. Other than that, 69 is pretty much the same as a 68, meaning numerous detail differences between it and earlier models---for example the rear suspension and having a two piece steering column and headrests on the front seats.

A few late cars came with factory sunroof. If this is one of them, it's worth saving the entire roof (cut off at the bottom of the pillars) if the car is truly beyond repair.
