Hmm, shouldnt there be a stamp or markings or a part numbers printed somewhere on the diff?

 

well there are a stampings on it but the numbers i ran i kept getting 2 diffrent results some people say its stock some say aftermarket

 

How about posting what car and model it's for.

 

Seriously, a bigger pic + a pic that shows a split in the case (if there is one) would do alot of good. It sure doesn't look factory or like my kaaz, that's for sure. Where in Washington are you? What are the numbers on it?

 

car its in 86 rx7 with 2jz
i dont have a bigger pic theres no split in the case its solid and i belive the number were something like
fk1425 i cant seem to find were i wrote down the numbers if i pull it out i try and borrow a camera to get better bigger pics

 

i got a better pic is this a vlsd thanks for the help

That is a torsen style diff, not stock to an FC. If it's turbo size it's from an FD, if N/A size I have no clue what it could be from.
