Who knows rear diffs?
 

Recently bought a new gearbox and diff for my impreza and upon changing the rear diff I noticed that when you look through the holes where driveshaft goes there is no bar in the way like normal ones. What could this mean? im getting excited and thinking ive bought a lsd for stupidly cheap lol


Cant really find much info online and all the diffs ive handled have the bar in the middle.
