I have a late model double synchro e153 with lsd. From all the research I've done on the net it's difficult for me to say if this is the standard diff or not. I remember reading once that if looking in there is a small hole it is TRD but there was no pics.
So I have these 2 pics of both sides of my diff. Can anyone tell me if it is standard or TRD or otherwise?
Thank you

not the std viscous LSD

and its not the standard non lsd is it? I hope not

It's not the standard open diff or the standard LSD. It must be some sort of aftermarket LSD.

Could be wrong, but from memory it is the TRD diff...
