The lower half would be handled by an EJ cross member with ea82 control arms. Seeing as EJ control arms are about a 1/4" longer then ea81 arms and the pivot points are moved two inches out on each side. Since you can put EJ axles on an ea82 car if you move each side out two inches it would accommodate the Tribeca axles. This would also correct the negative caster built into these cars.Just eye balling it the radius rods would be able to just be extended and use factory mounts. Best I can research you could use Tribeca inner tierods to soak up the extra length.
Two things I haven't been able to figure out are: How big the bolts are on EJ control arms vs the EA cars, and if The xt6' s have the same size bolt as the EJ cars? The second is since Tribeca's have male axle ends can you just pop the stubs out of the diff and slide in the Tribeca axles? Yes I know you'd have to split the cases. Oh this is a five speed not the stock four speed.
All this is just a theory a lot of it is based around how SK'o had his bobbed brat suspension set up, although I wasn't able to find much on that. Thoughts and input would be appreciated.
