Not sure they would've as it would've just missed Burradon for no real benefit.
The A189 ran via Burradon, Annitsford and High Pitt - have to remember Cramlington and Killingworth didn't exist at all pretty much so not much point going via Dudley North.
I'd assume the services would've still been the X25/X26/363/364 on those respective routes on whatever number they had back then.
