when doing your search on car-parts.com specifiy "carrier" in the search not "differential". It will then give you a list of options to choose from as far as ratio and type. I used a 1993 vehicle for the year so I would be sure to get the 4.88 option. Im not sure what year the 4.88 option started but I didnt get the choice when using 1990 model year.
