1998 ranger rearend help

[montalvo]

Hello all! i am having a hard time finding a matching rear and for my truck, the code is 3 73 88 8d08... the only thing i can find is one out of a 99 ranger with the code 3 73 75 8l16, can i use this one or does it have to be the same code? any help would be greatly appreciated, thank you.
