You have a 10-bolt 7.625 and in all proability a 2-series carrier. Unless youhave the ring gear for a 2-series carrier it will not work. Also you in most cases you do not have a Limited slip carrier. So with little knowledge you are buying part and you don't know what you have and a gear change is not a DIY type project..
