That's probably going to be a non-turbo R32 diff. R32's came with the small/solid front mounting points. All of the non-gtr R32's I've seen were 5-bolt. All the GTS-T's were VLSD, so that is ruled out. Look on the ring gear for a stamping like 49:12, which will be the gear ratio.
Just a point of info, both S15 diffs (vlsd, hlsd) have the larger front mounting points like an S14, and are also 6-bolt.
