need help! differential question
 

okay i have a 95 na supra that i plan on doing a full tt conversion. i bought a lsd 6 speed differential off a guy about a week ago that he said came off of a 94 tt so it should be a lsd. my question is, is there anyway to make sure that it is an lsd without pulling the pumpkin apart? and i need to know if it actually is off a tt or not. its a lot bigger than the one i took off of my car.
