76cruza

Hello All, wondering if anyone has any experience or knows if a later 2016 onwards 70 series gearbox will couple without mods to our 2008 or, earlier 70 series models? Or maybe there is somewhere/someone I could ask? reason I ask is I would like to drop the revs in 5th gear, and it may be cheaper to go the whole later model box if it works, than just replace the 5th gear cog
