I have a E3O 325i touring 1990. I have purchased a differential from a breakers yard to swap over. The differential looks slightly smaller to one fitted on my car. I think I have been sold one from a 320i model.
I know the gear ratios will be different, but will I still be able to fit this without having to change the drive shaft. Also is the diff from a 525i of a similar age the same.
Many Thanks
Yas
