I had a 2+2 diff {std I bet} but left it in the car when I sold the shell, to lazy to take it out
I take it a R180 and R200 are a straight swap with each other or are the shafts n mounts needed?
btw, Does the diff from a 200sx {S13 or S14} fit into a Zed?
For the R200 swap you need the R200 moustache bar, although I have heard rumours that you can turn the R180 bar around and redrill the diff mounting holes, probably work-ish! But it's a fairly straight forward swap other than that. If you're keeping the UJ half-shafts then you need the correct output shafts for the R200, course if you get one from a Z then you'd be OK. Alternatively you can swap to stronger 280ZX CV shafts (if you can get some) but you then need adapted companion flanges at the outer end, available from

The 200SX diff swap is a lot tricker as it's a short nose version of the R200. Although the rear mount is the same, as the diff is shorter you need to fab up a completely new front mount system, and of course have a longer propshaft. I'm currently attempting it myself, although being greatly hampered by my inability to weld. I'll get there in the end.
One more semi-option is to take the viscous LSD centre from an 200SX diff and fit that into a Z R200 but you'd have to then use the CV shafts from the 200SX, modified for length, and still need to figure out how to connect them to the hubs - easy
- a lot of work for only a viscous LSD.
