z31 differential question

[jkgts1]

I just got my hands on a R200 diff from a 85 300zx turbo. Is this R200 a 4 pinion or 2 pinion? Can anyone answer this for me?

Thanks

I think the Z31 open diffs used a 2 pinior, easy enough to pop the cover and check, although honesly there is no substantial difference in performance, 87.5-89 turbo's got LSD
