These are some photos I took one afternoon when I was board and had nothing else to do so I bolted some parts together,
160J cross member
R200 CLSD HR31
Stock R200 half shafts (a bit to squashed up might work but prob would need shorting)
Z31 5 Stud hubs
HR31 Vented discs (have internal drum handbrake) (re-drilled to suit 5 stud).
R32 Twin pot rear brakes.
I later found some random brake lines at a local store I have no idea what they are from but they fit
Everything bolts straight together only custom work was redrilling brake discs I did this with a battery drill (I don't ever plan on using them will buy new discs).
It just gives you quite a bit of extra toe in but I think that could be adjusted out with a Datsport ARC (I'll let you know one day).
You need to run rear coilovers with this setup as there isn't an area for a spring.
Another option is 240k rear arms. 2 of the 4 bolts that hold the rear drum brake plate on bolt directly to the 240k arm. The hubs slide straight in with no bearing changes.
You will need to weld on shock mounts though, not a hard job.
