how many splines are the rear axles in a 89 camaro rs. its the stcok borg warner 10 bolt mini or whatever. ive searched and cant figure it out.. HELP!!!

Little confused on whats under the car. You have a stock 10-bolt and not BW diff. In most cases you have a Atuo with a 2:73 ratio and since 1989 was the changeover, My guess is youstill have 26 spline axle shafts. Reason: GM had a lot of 10-bolt 2:73 ratos with 26 spline axles in the inventory to use up. Or pull a axle shaft and count the splines.
