Hi Guys. Found a guy selling a couple third members that he's calling LSD. Over here thats anything from a true LSD from the factory to any of the various lockers. I'm attaching some pictures can you guys tell what kind of locker is installed? He also says they'll fit 40's or 60's. I'm running a 40 series SF now but will be swapping in a 60 series FF rear. Will these work in both? Thanks for the help.
