sdaztecs92115 Posted November 18, 2011 Share Posted November 18, 2011 Hi all, I am interested in installing a posi unit in my 1970 Monte. It has a 10 bolt rear end. The ring gear is 8.2, correct???? Thanks! Quote Link to comment Share on other sites More sharing options...
cbolt Posted November 18, 2011 Share Posted November 18, 2011 More than likely, yes. To be sure check this section for past posts on how to identify the different rear ends. The 8.2 and 8.5's are identified by the pinion nut size and the housing "tabs". There are good pictures in recent posts. Quote Link to comment Share on other sites More sharing options...
