The differences with the crownwheel bolts are the same with the S13 install into the S12 if i remember correctly. Been 2 years since I did it but I do remember something like that.
I was under the impression that you have to use S15 shafts with the helical diff, judging by some people searching for S15 shafts on sxoc.
Thing is, they're overpriced. There is an S15 diff on sxoc for sale at £450 which is silly when a quaife would only cost £100odd more
