How hard is it to find a zc lsd tranny and how can you tell it has lsd by just
looking?

 

Yes it is hard to find. Haven't seen any for a while. and Yes look through the differential where the axels go in. If its an unobstructed whole clear through it its LSD if you see a round shaft going through its its a normal differential and non lsd.

 

may the force be with you. its possible but you have to cross your fingers.
