(DRIVETRAIN) Another Differential Swap Question

I did not see anything about this anywhere so I thought I'd ask.

Will the Torsen unit from an FD 2x turbo work in a 85 GSL rear housing?

Thanks

Did a little bit of research, and it looks like the years for the miata torsen swap are 94-97.

even better I found a part number for the diff!!

You guys considering the torsen swap might want to take a look at this, It looks like the axes have to be slightly lengthened for full spline contact.

However these upraded axels are stonger to begin with, and stonger axels never hurt anyone.
