Will 8.8 third member fit 2nd gen?

Anyone know if the new e-locking third members can be swapped into 2nd gens?i havent compared bolt patterns and obviously don't know if the axles and splines are the same, but have been reading hints on Google searches that they may be swappable. I'm assuming only on non-locking 2nd gens because of the e-locker being a seperate actuator before to an internal one now. All I've learned by checking the forums is a lot of people are confused about Toyota rear differential ring gear sizes haha.
