final drive gears

[ae86 slide]

im currently looking at buying some 4.556 diff gears off yahoo auctions but in the description it never says anything about what diff there for, zenki or kouki.
are there only differences in centres and axles between zenki and kouki?
and are the ring and pinion gear sets all the same?
if that makes any sence.
cheers jase

There is no difference in the Crown wheel / pinion for any T series diff - TA22 all the way to AE86. Aside from the actual ratios of course. So kouki/zenki/whatever it will fit another t series housing.
