help with part time 4x4 options 80 series (1 Viewer)

[twistinchassie]

Gday,

I have a 80 1hdt turbo auto cruiser thats full time and looking to go part time to alleviate the issues with big lift and constant 4wd.
now I also have a AVM part time kit hubs and spool, which im lead to believe are pretty weak.
i also have a 80 1hz manual DX with the part time factory hubs and transfer.

what option is best in regards for strength,

install the part time kit

swap the hubs and transfer from the dx into the gxl

swap just the factory hubs and use the spool for the center diff.

Thanks.
