I do know that there are a number of different diameters available for different applications using the same backing plate, but bigger isn't necessarily better.
It could easily cause premature lockup on the rears as the rear unloads under heavy braking, and you'll get a slightly longer pedal.
Back to your question, do you know your build month?
I can do more checking tomorrow if it helps.
