Just something about the R31 skyline diffs, if you do decide to get one shortened to suit + retain the discs + stud pattern for the 1200..
The Pintara R31, which is the CA20E 4 cylinder model, has only got a 2 pinion centre with smaller axles (lower spline count), whereas the six cylinder R31 skylines - the skyline runs the same basic 4 pinion, 28 spline setup as the VL turbo, V8 commos, XR6 etc.
However the six cylinder rear end would be either 3.7:1 or 3.889:1 ratio, where the 4 cylinder one is 4.1:1.
The gun setup would be an LSD or spool in a skyline housing with a pintara 4.1:1 gearset (or even lower, I believe the same basic BW diff is in a huge range of aussie large cars). That way you'd get a decent gear ration, the discs you want, and the strongest axle setup.
The only bad thing about the R31 rear discs is the calipers have a habit of seizing up (so use reco ones), and the handbrake, at least in the R31, isn't very strong. Though that may be rectified somewhat by only having to pull up an 800kg car, not a 1300kg one...
