trying to get front wheel bearings for my 91' lude 110kw and cant find any on ebay

there is many that fits 90' same luds and i ordered one, but the guy told me that they don't fit my car...
confused now :/ is it true that the same model, but a year different lude bearings can not fit or its just their online check system rubish?
any help will be much appreciated
