Korando 1998 rear differential

Hi there, im from Croatia and not speaking Russian so i hope its ok to write a question on English, to get on case im proud owner of Ssangyong Korando 1998 year. and im having a rear differential problem sadly so i was wondering does maybe differential match from other car another manufacturer( some Mercedes models maybe since there is motor with their licence) cause its hard to find original parts for Korando here in Croatia. Hope someone can help me. Thanks.
