CHOICE S13

Hey guys, so I installed a disc style limited slip in my 90 s13 coupe. My issue is there is approximately 1/16" if not a little more play in both stub axles. There was no play in my open diff stubs. It is a used unit I bought off a very knowledgeable guy that has built several 240sx's. There was no play in the car they were pulled out of. The stubs went in fine but again the play worries me. I will be taking my micrometer to both sets of stubs tomorrow just to double check. Any advise or knowledge would be greatly appreciated.
***I dont know the brand of diff any way to tell or if you know from the pic?**
