That microfiche was obtained a long time ago...we had similar files for a 70 L78 car from Canada. [circa 1990]
They finally realized the microfiche showed a lot of info on other cars, many the hi-perf models. If you have the VIN and options it is easier to 're-create' a car
Not sure when they stopped supplying this info...but it has been awhile.
Good luck with the car.
