Whaddup guys?

I have recently acquired the rear suspension setup from an unknown model FC that i wanna transplant into my GSL-SE, independent rear will really help me at autocross and getting aftermarket LSD units for FCs are way easier than for SA22s, besides, i also have a set of Tein coilovers for it waiting

My question: How do I determine if the rear setup (it's complete, minus springs/shocks) has an LSD? It isn't in my possession yet so I can't just spin the axles and find out. Any part # to look out for?

Also: Have any of you seen/heard of this suspension swap done before? I'm just looking for some tips/tricks/help to make my conversion as smooth and as efficient as possible.

Thanks a bunch and keep up the excellent tech posts!
