Qashqai drive shaft

[Levitric]

Good afternoon, the wife’s qashqai is in garage for what sounds like CV noise. I bought two drive shafts from AUTODOC as the garage couldn’t get hold of any. The offside drive shaft has fitted ok but the n/s doesn’t fit. The new one has 26 teeth differential side but the old one has 27 teeth. Can anyone shed any light or wisdom on this please. It is a 2019 1.5 dci N conecta.

I guess you could swap the inner joint for the original one that will fit the gearbox, as a last resort?
