I did a search, I was just trying to figure out why people choose this over something of the same brand of car it's going into. I've done the research, and the bearing sizes, spline count and so on go to the 8.75". I just haven't had to choose one or the other, but I'd most likely choose the mopar over anything else because that's what kind of car it's going into. plus, just recently am I able to drive, let alone test two comparable rear ends.
