Hi my good friend Ken!
You can ID the year of your frame by it's serial number and then referencing this chart at the this link:

The last year for the "Brampton" fastback was 1977 (maybe early 1978?) based on seeing the non-fastback version for sale in shops during 1978.
Can't help with the BB cutouts, but I am curious too.
